Introduction to Algebra

x-3=4 is exactly the same equation as:

An equation is just a mathematical statement that two things are:

For a + b = 3, if a = 1, then b =

In arithmetic, the only thing that was ever unknown was:

____________ equations form straight lines when you graph them.

Algebra is not used in this:

In the algebraic equation 3 + 4 = x, x = _______

x (or any other symbol) can stand for different values in different problems.

One of the main goals in algebra is to find out what the __________ in equations are.

6y is the same as 6 + y

Algebra is a lot like

30x + 6x = 3x + 15. The x's in this problem can stand for different values.

Which is NOT one of the four orders of operations?

If a value in an equation can change, it's called a:

The same symbol repeated in an equation represents the same unknown value.

(6)(7) is the same as:

The default operation of algebra is:

When we see "ab" in an algebraic equation, we use this operation:

(a + b) (x + y) is the same as (a + b) x (x + y)

In algebra, when we don't know what a number is yet, we use this in its place:
