Similarly, the expressions in an equation remain balanced when we add the same quantity to both sides of the equation. In this section, we will solve equations, remembering that what we do to one side of the equation, we must also do to the other side.

If we find one counterexample, one example that shows that subtraction is not commutative, the general property (using $a$ and $b$ ) does not exist. where $a$ and $b$ are any real numbers (like...If we find one counterexample, one example that shows that subtraction is not commutative, the general property (using $a$ and $b$ ) does not exist. where $a$ and $b$ are any real numbers (like $-6.4$ , $\displaystyle \frac{2}{7}$ , $\pi$ ). Any real number can hide in the $a$ -box or the $b$ -box. If we find one counterexample, one example that shows that division is not commutative, the general property (using $a$ and $b$ ) does not exist

If this is true, then the language of mathematics is numbers. The earliest use of numbers occurred 100 centuries ago in the Middle East to count, or enumerate items. Because of the evolution of number systems, we can now perform complex calculations using these and other categories of real numbers. In this section, we will explore sets of numbers, calculations with different kinds of numbers, and the use of numbers in expressions.

Because of the associate property of addition, when presented with a sum of three numbers, whether you start by adding the first two numbers or the last two numbers, the resulting sum is the same. How...Because of the associate property of addition, when presented with a sum of three numbers, whether you start by adding the first two numbers or the last two numbers, the resulting sum is the same. However, because subtraction is the opposite of addition, in Figure 1.5 we attach an arrow of magnitude (length) four to the end of the first arrow, but pointing in the opposite direction (to the left).
