Adding a negative number to a negative number makes a larger negative. In order to solve this you add the numbers together as a positive then add a negative sign.
When it comes to numbers (this question was asked in the "Math and Arithmetic" category), adding a negative number to a positive number always equals a negative number.

26, in that situation just add the negative number to the answer to find the variable
Let's call the number x. x-25=-51. Add 25 to both sides. You get x=-26. The number is negative 26.
To solve -2 plus 5 equals, it's probably easier to start with the positive number and add the negative number to it. The equation will look like this: 5 + (-2) = Because you are adding a negative number, you actually have to subtract the 2, rather than add it, so your answer will be 3.
Positive plus positive equals positive. Negative plus negative equals negative. Positive greater than negative equals positive. Negative greater than positive equals negative.
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.
Negative
You get a positive Number answer.
When you add a negative number, the one on the right side gets cancelled out. E.g. -3x + - 3x = -3x
Adding two negative numbers always gives a negative number.
