Which description of the algebra tiles below are correct?

• The tiles only represent positive values with no indication of variables.
• The tiles represent positive and negative values, with rectangles and indicating the variable (x) and squares indicating ones.

• All tiles are the same shape and color, representing a single variable.
• The tiles are used solely for geometric calculations, not algebraic expressions.

What is a zero pair?

• A zero pair is a single number that equals zero.
• A zero pair is a pair of numbers that add up to zero, typically one positive and one negative number.

What ever you do to one side of the equation, you do to the (a)   side.

When variables are on both sides, you should move the (a)   value variable by using the inverse operation.

Answer explanation

You will move the smaller value variable (-6x) to the side of the larger value (-4x) variable by using the inverse operation (+6x).

Remember, a negative number may be larger, but actually be the smaller VALUE.

For example:

6 is greater than 4 BUT

-6 is less than -4
