When you add a positive number and a negative number, it is the same as subtracting the negative number from the positive number. For example:
4 + (-5) is the same as 4 - 5 (which is -1).
One more example:
(-10) + 15 is the same as 15 + (-10) (because it doesn't matter what order you add numbers), which is the same as 15 - 10. (which is 5).
A bit more:
That depends on the value of the positive (plus) and the negative (-) numbers. For example, if you add a positive 5 with a negative 3 (-3), the answer will be a positive 2. But if you reverse it and add a negative 5 (-5) with a positive 3 (+3), the answer will be a -2.
3 is a number and plus 3 is adding three to a number
You'll get an odd number when adding two evens (which will be even) and an odd number.
the mass number of an atom is the number of protons in an atom, plus the number of neutrons.
No. Adding two negative numbers will give a number which is more negative.
plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
Adding a negative number is just the same as subtracting a positive number. So 3 plus (-4) is the same as 3 minus 4. The answer to 3 - 4 is the inverse of the answer to 4 - 3 So if 4-3=1 then 3-4=-1 Other useful rules: Taking away a minus number is the same as adding a plus number. Subtracting a plus number, or adding a minus number, is the same as taking away a positive number.
Adding zero to any number results in the original number, so 9 + 0 = 9.
If a perimeter of 8 is obtained by adding 5 and unknown number, then the unknown number is 3.2.
Adding a negative number has the same effect as subtracting a number. In this instance, -31 + (-46) = -31 - 46 = -77
Adding 7 percent to a number is the same as multiplying the number by 1.07. In this instance, 4100 x 1.07 = 4387. Therefore, adding 7 percent to 4100 gives 4387.
Adding a negative number is the same as subtracting the number. In this instance: 24 + (-8) = 24 - 8 = 16
