Mathematics is the language of science and Technology. It is required to understand the world around us and develop novel technologies in fields ranging from physics and chemistry to computing and engineering. For example, in the physical, chemical, and biological sciences, arithmetic describes and models the behaviour of matter, energy, and chemical reactions and predicts the attributes of various substances. In computer science, arithmetic creates algorithms and codes that power our digital world. Math holds significance in Science and Technology because it has practical applications in addition to helping people understand the world around them. Math can help address real-world problems, including devising new medical treatments, upgrading transportation systems, and developing more efficient energy sources. In short, mathematics is critical to scientific and technological advancement, and its significance needs to be emphasized.
The conventional discipline of 'mathematics' primarily concerns itself with numbers, angles, formulas, and the derivation of accurate solutions to complex inquiries referred to as 'problems'. For decades, mathematics has been regarded as a series of "problems." Many of the global population confronted the issue with trepidation, bewilderment, and difficulties in executing the appropriate measures. Mathematics has become an integral component of daily activities in the 21st century. The challenge for mathematics educators is to render the subject devoid of dread while enhancing its appeal through skills, tools, and innovative concepts. 

Significance of Mathematics
Mathematics is a subject, and we all know how crucial it is for kids to create their future from a different perspective. Mathematics is vital in all fields. Mathematics is present, whether in physics, chemistry, or accounting. It has a significant impact on our daily lives. It is fair to say that it has become an integral part of us. Imagine our life without it, like a boat without sails. It is startling to learn that we continuously use mathematics without realizing it. Mathematics is used in everything from making instalment payments to dialing a simple phone number. We benefit monetarily from the importance of mathematics education. It assists us in figuring out our daily, monthly, and annual spending. It teaches us how to budget our money and set priorities. Its expertise is also necessary for financial investments. Only when we can compute statistics can we invest in real estate, bank plans, the stock market, mutual funds, etc. This would not be feasible without numbers and maths. Therefore, we can claim that mathematics plays a role in making our lives easier by assisting us in making better decisions throughout the day and by making us more computer aware.
 
The role of mathematics in the 21st century
Today, it is expected that teachers will encourage pupils to think creatively and critically, particularly in the field of mathematics as well as other subjects. Undoubtedly, this task is more difficult for mathematics teachers, as incorporating creativity into logical topics can become rather demanding. Since mathematics is the key skill for the future due to its capacity to explain things rationally and back up our thoughts, discussing mathematics’ function in the 21st century is strongly connected with creative and critical thinking. This is because mathematics is a fundamental skill for the future. It starts off by instructing students on reasoning and problem-solving.

Relevance of Mathematics
The fact that mathematics is an art form has been demonstrated by all of the leading mathematicians and by regular individuals. In the pursuit of beautiful theorems, what is the primary objective of mathematics, and how does one go about studying it? This is why we go beyond the immediate needs of science and other types of applied mathematics and guide those needs into fruitful realms of formalism that would otherwise be worthless. Mathematical truths are indeed objective; however, selecting these truths is subjective. In the process of filling in the body of knowledge about each subfield, we can voice our own worries, and it is not difficult to find evidence in the history of mathematics that demonstrates that mathematics would have been around if we had been different.

Critical and creative thinking
Students' interest in mathematics has been rekindled due to the creative and analytical approach to dealing with the subject matter. Gone are the days when mathematics was limited to a number game and formulas. Now, students are interested in understanding mathematics. It is common knowledge that mathematics is a topic that can lead to many opportunities for pursuing a career in the technological field. Not only does mathematics help students understand various topics, but it also helps them become aware of future talents, such as their ability to think critically and creatively. This is because these skills will be in high demand in the future labour market and will be required in every industry to succeed and advance.
Thinking that is both critical and creative is regarded as a skill that is quite significant in both one's personal life and one's professional life. In order to find experts who are capable of raising the bar for the company's growth and developing unique ideas to solve a variety of obstacles and modern problems, employers are looking for them. It is possible to identify critical and creative thinking as the solution to challenges prevalent in the 21st century. 

Problem Solving and Reasoning
Today, more than ever, the capacity to think critically and solve problems is a must. The ability to think critically and solve problems is a talent that may be refined through studying mathematics, which requires learners to do more than just memorize answers. Kids who take math classes are less likely to experience needless confusion in their lives. 
Math classes also help students develop traits like the capacity to reason, think abstractly and creatively, communicate effectively, think spatially, and solve problems. 
A mathematical mindset is one that uses mathematical concepts to find practical solutions to everyday issues. Mathematical reasoning and problem-solving using real-world examples encourage students to recognize and articulate issues, as well as to choose and implement suitable ways for resolving them. Increasing students' mathematical competence in both known and unknown circumstances is the primary goal of teaching mathematics with a contemporary perspective. Cases in point include discrete growth and decay, decision-making, financial modelling, metrics, network analysis, route and project planning, etc.

Mathematical reasoning
When students are given tasks that include mathematical reasoning, they are motivated to think of as many examples as they may potentially think of. To encourage students to analyze and recognize patterns, teachers need just to urge them to do so. Through applying reasoning, one can establish a solid basis for the pleasure of discovery by figuring out the most fundamental notions. Students are more likely to experience "light bulb" moments in the classroom when they are allowed to solve mathematical problems independently. This is the most effective way to boost students' real interest in mathematics. There is nothing that works better than allowing students to find out answers on their own. The function of mathematics in the 21st century, or more specifically, the role of IB math and IB mathematics, is to encourage students to figure out the answers rather than telling them to do so. Due to the fact that it actually engages students in the subject matter, it is progressively altering the way in which students perceive mathematics as a subject. This allows students to comprehend mathematics’ role in the contemporary world.

The main objective of mathematics today
Mathematics provides an efficient method of developing mental discipline and inspires logical reasoning and mental precision, which is particularly useful considering the growing demand for modern abilities such as creative and critical thinking. In addition, it is also an essential component in comprehending the fundamental aspects of various other technical and non-technical courses, including but not limited to physics, music, social studies, and so on.
 
Necessity of Learning Mathematics
The field of mathematics is based on the work of many philosophers from different parts of the world and eras. The ability to measure correlations, comprehend patterns, and foretell the future are all gifts bestowed by it. Both the world and mathematics have a role in our understanding of each other. There are numerous marvels in this interconnected world. We need to know why mathematics is important to studying the current world. These relationships and opportunities are revealed by common mathematics. Our culture and economy will be more inventive if young pupils can use these abilities early on. When it comes to communicating and comprehending on a global scale, mathematics is a potent weapon. Students can use it to address real-world problems and better understand the world. Students gain a new perspective on familiar material when they reframe mathematics in a global framework, which, in turn, makes the subject more relevant and engaging for them.

Summing up!
The growing importance of mathematics in the 21st century has resulted in an increase in the pupils' capacity to comprehend these concepts. Mathematics is a topic attracting more students than ever before to indulge in it and discover the rationale and reasoning behind everything they go through in their personal and professional lives. It has moved beyond numbers and is now reaching a far wider audience. Indeed, it is a path that leads to various destinations and encourages the development of talents relevant to the 21st century worldwide.
