Write two subtraction equations to show to find 15-7

Answer 1

You can express the subtraction equation \(15 - 7\) in two ways:

1. \(15 - 7 = 8\)
2. \(8 + 7 = 15\)

These two equations show the relationship between the numbers involved in the subtraction. The first equation directly calculates the difference, while the second one shows that adding the difference (8) back to the number subtracted (7) returns you to the original number (15).
