Even though counting is first taught at a young age, mastering mathematics, which is the study of numbers, requires constant attention. If it has been a while since you have studied math, it can be helpful to review basic topics. In this tutorial, we will focus on numbers used for counting as well as the four arithmetic operations—addition, subtraction, multiplication, and division. This tutorial is not so necessary for those who already have a solid foundation in mathematics. We will simply discuss some vocabulary that are useful throughout our study of mathematics.
