Express each equality property in its equivalent equality equations for each scenario:

If two people start with the same amount of money and both spend P5, they still have equal amounts left. (SUBTRACTION PROPERTY)

Back

Spending the same amount

Let x be the initial amount of money each person has.

After spending P5:

x−5 = x−5

Front

If two people have the same amount of money, and both receive a P10 bonus, their total money remains equal.

(ADDITION PROPERTY)

Back

Receiving the same bonus

Let x be the initial amount of money each person has.

After receiving a P10 bonus:

x+10 = x+10

Front

If two identical boxes each contain 5 apples, and we double the number of boxes, both will still contain the same total number of apples.

(MULTIPLICATION PROPERTY)

Back

Doubling the number of identical boxes
Let each box contain 5 apples.

If there are initially 2 boxes, the total apples per person is:

2×5=10

Front

If two people have the same amount of money and both divide it into 4 equal parts, each part remains the same.
