Integers are the set of whole numbers and their opposites. Whole numbers greater than zero are called positive integers. Whole numbers less than zero are called negative integers. The integer zero is neither positive nor negative, and has no sign. Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. Positive integers can be written with or without a sign. an example with numbers is 17positive and 17 negative both are 17 (clicks/jumps/etcetera) away from 0. There is no 0 positive or negative.
Divide the balance by 2. this gives you 117.62. Divide the overdraw by 2 giving you 22.79. Add 117.62 and 22.79 this gives you 140.41. now do the math. 235.24-140.41-140.41= -45.58. so each check was 140.41
