9. Backwards Words
Add 3 and 7 =
3 + 7
The sum of 3 and 7 =
3 + 7
3 increased by 7 =
3 + 7
The total of 3 and 7 =

3 more than 7 =
7 + 3
3 added to 7 =
7 + 3

10. Backwards Words
7 subtract 3 =
7 - 3
The difference of 7 and 3 =
7 - 3
7 decreased by 3 =
7 - 3
7 diminished by 3 =
7 - 3
7 less than 3 =
3 - 7
7 subtracted from 3 =
3 - 7
