  10. You can Simplify the algebraic expressions to help understand it and solve it faster. Simplify absolute value expressions. Find the distance between two points. and follow PEMDAS to help solve it and get it correct. Inverse operations can be used to solve algebraic problems. There are four mathematical properties that deal with inverses. The additive inverse property states that when you add a number to its opposite, the result is always 0. The multiplicative inverse property states that when you multiply any number by its opposite, the result is always 1. The additive property states that when you add any number to zero, the result is the same number. The multiplicative property states that any time you multiply a number by 1, the number does not change.
