What are the rules for adding and subtracting integers?
when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative
How do you substract negative numbers?
Subtracting negative numbers is exactly the same as adding the positive number.
Why multiplication of negative numbers equals positive?
When you multiply any number by a negative number you reverse its sign. So positive numbers become negative, and negative numbers become positive. That is the meaning of negative multiplication; it is reversal. This is similar to the way that adding a negative number has the same effect as subtracting a positive number. Negative is the opposite of positive.
What is equivalent to adding a negative number?
Subtracting its additive inverse. (In principle, this is valid for adding positive numbers as well.)
How do you get a negative answer when subtracting two positive numbers?
Have the second number be greater than the first.

What is a negative take away a negative it equals positive?
The result of subtracting a negative number minus a negative number can be positive, or negative, depending on which of the numbers is larger. It can even be zero.

If your positive and negative number are the same does it become a negative number or positive number?
It depends on what you are doing to the two identical numbers. If you are multiplying them, it becomes a negative. If you are dividing them, it becomes a negative. If you are adding them, it will always be zero (e.g., 2+ -2 = 0, etc.). There are two ways to subtract. If you are subtracting a positive from a negative, the number remains negative. If you are subtracting a negative from a positive, or a negative from a negative, the negative becomes a positive and you just add from there.
What is the rule for subtracting negative numbers?
e.g. 'a' - ( -a) becomes a -- a a + a = 2a Here with a table for manipulating 'double' signs. = + = - = - = + NB If no sign is shown in front of a number , then read the number as plus(O).
Why can you subtract from a negative number?
Because numbers don't stop. Think of a number (positive or negative) as a point on a number line. You can move to the right by adding to it and to the left by subtracting from it.
What is a negative subtracted by a negative?
Subtracting a negative number has the same effect as adding a positive number - think of it as moving right on a number line whereas, subtracting a positive number will move you left on a number line.
What is -7 x -5 plus -10?
The answer 25. Multiplying two negative numbers results in a positive answer. Adding a negative number to that result is the same as subtracting a positive.
