Look at the equation:
7 minus 3 equals 4.
The number 7 is the whole.
The number 3 is the part that was taken away.
The number 4 is the part that is left.
If you take one part away from the whole, you get the other part:
7 minus 4 equals 3.
So, to find the missing part, you need to subtract the known part from the whole.
Let's solve this equation,
The whole is 9,
one part is missing,
and the other part is 5.
To find the missing part, subtract the known part from the whole:
9 minus 5 equals 4.
So, the missing part is the number 4.
