2 - -9 = 2 + 9 = 11
987 minus 789 equals 198. This calculation involves subtracting the hundreds, tens, and ones places of the two numbers. In this case, 9 minus 7 equals 2 in the hundreds place, 8 minus 8 equals 0 in the tens place, and 7 minus 9 requires borrowing from the hundreds place, resulting in 10 minus 9 in the ones place.
To solve the equation "x - 9 = 16," we need to isolate the variable x. Adding 9 to both sides of the equation, we get x = 16 + 9. Therefore, x = 25. So, 25 minus 9 equals 16.

120 minus 87 equals 33.
It is: 132 minus 99 = 33
33 - 9 = 24
627.20 - 33% = 420.224
7/11 equals 21/33 1/3 equals 11/33 21/33 - 11/33 equals 10/33.

-96 = 33-y -96-33 = -y -129 = -y y = 129 Remember a minus divided into a minus is equal to a plus.
9-3=6
