![]() Furthermore, it's possible to reduce the two into one in such case according to the following rules: Observe how whenever we had two signs next to each other, we have to put the negative number in brackets. ![]() See a few examples of adding and subtracting integers below: To find a - b, move b positions from a:.To find a + b, move b positions from a:.Look for a on the negative and positive number line.Suppose that we have integers a and b, and let's explain how we can find a + b and a - b. When adding and subtracting integers, it's a good idea to keep the negative and positive number line from the above section in mind. Given a positive integer, we can also find the sum of digits in order to determine the divisibility of the number. The differences in negative and positive number rules are small, and we point them out in each section below. In particular, we can add, subtract, multiply, divide, raise to a power, take the root, calculate the logarithm, etc., using those numbers. This way, a number and its opposite are at the same distance from 0 but to the opposite sides (this distance is called the number's absolute value).Īrithmetic and algebraic properties apply to all the values on the negative and positive number line. On the other hand, if we go left, we meet the same numbers but with minuses: -1, then -2, -3, and so on. In other words, if we start at zero and go right, we'll visit 1, then 2, 3, and so on. Negative numbers are the mirror image of positive ones with the mirror put at 0. ![]() In essence, the line tells us where one number lies with respect to the others: is it larger (to the right) or smaller (to the left) of something else? When they introduce us to mathematics, we count to ten on our fingers, so we know that, for example, 2 comes after 1 but before 3.
