In any subtraction sum, such as 8 - 3 = 5, the first number is the minuend, the second number is the subtrahend, and the third number, following the equals sign, is the difference.
If you're adding: Ex. -3 + 15 (-3, -2, -1, 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15) = 12If you're subtraction: Ex. -17 - 20 (add the opposite, so problem really equals 17+20)= 37If you're multiplying: Ex. 5 x -10 (one negative equals negative answer. both positive or negative equals positive answer.)= -50If you're dividing: Ex. -100/10 (same rules as multiplication)= -10
x=-3
A negative plus a negative equals a negative because the operation you're doing is equivalent to subtraction. If you wrote down a sum "negative 3 plus negative 7" it would look like this: -3+-7 which is the same as -3-7 Whenever you add a negative number you are actually taking more away, and this is why a negative plus a negative equals a negative - You start with a negative number, and are taking even more away, so you will only ever end up with a negative number.
-3/16 since the answer is negative (the second number is larger) and the problem is subtraction you minus the second number from the first then make the answer negative and you have the answer
-5 - 3 = -8
3
Explain that the negative(-3) can be moved and become a subtraction sign. -3+5=5-3
The associative property refers to mathematical expressions where the order of the number is totally interchangeable and will still yield the same answer. Changing the order of a subtraction problem will give you a different answer. For example, 4 - 1 = 3. When switched, 1 - 4 does not equal 3. It equals -3.
Negative 9 + positive 3 = -6 and negative six - negative 3 is -9.Vanessa Hudgensage 12
-2 - (-5) = -2 + +5 = +3. (+3 is not in the set of negative numbers.)
It depends which number is larger. If if subtract a negative number, you are additioning it; yet if you are adding a negative number or subtacting a positive number, you are just subtracting. -x - (-y) = -x +y - (-x) + (-y) = x - y -3 - (-5) = -3 +5 = 2 -4 - (-2) = -4 +2 = -2
