What is the math word that refers to the answer of an addition problem. (Hint: The _____ of 2 plus 2 is four.)

Sum

200

If you do something to one side of the equation, you always have to....

...do the same thing to the other side.

300

Solving an equation by "isolating" the variable means...

...getting the variable (x or y or whatever) alone on one side of the equation; also acceptable to say "undoing" whatever has been done to the variable to get it by itself.

400

State the inverse (or opposite) operations. (Which ones go together to "undo" each other when solving equations?)
