If you don't know something in a math equation you can replace it with a variable and then solve it algebraically.

You use variable in math problems to help you solve the answer. For example, you could do 50+50=a. The (a) would be the variable. Or for that same problem you could do 50+y=100. Then the (y) would be the variable.

OK. Bring it on.

Keep working the problem until you solve it. Get some help if necessary, but not during a test!

An algorithm is the series of steps to solve problem, so you would be looking for the series of steps to solve a math problem.

The number 3 equals x when it has the same value in an equation. This is used to help solve a specific problem in math where certain variables are unknown.

You isolate variables in math because the point of an equation is to solve for the variables. By isolating the variables you have learned what that variable stands for and thus solved the equation.

you solve the problem in your head with no help from calculators or number lines ect..
