In this section, you will learn how to solve equations that contain unknown variables. You will learn how to solve equations mentally by using the multiplication table and you will also learn how to identify a solution to an equation with given numbers as well as by using inverse operations....
Equations can be used in math to solve for unknown values. Sometimes, equations have multiple variables in them which make them more complicated to solve. Equations differ from anumber sentenceby the fact that they usually contain variables and number sentences do not. Number sentences contain oper...
