What happens when a plus and a minus are together?
Addition and Subtraction Two ‘pluses’ make a plus, two ‘minuses’ make a plus. A plus and a minus make a minus.
What does a positive minus a positive make?
Rule 1: Subtracting a positive number from a positive number – it’s just normal subtraction. For example: this is what you have learned before. 6 – 3 are two positive numbers. So solve this equation the way you always have: 6 – 3 = 3.
Why do 2 negatives make a positive?
Each number has an “additive inverse” associated to it (a sort of “opposite” number), which when added to the original number gives zero. The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.
What does distribute the negative mean?
Distributing a positive sign makes no difference in the signs of the terms — the signs stay the same. When distributing a negative sign, each term has a change of sign from negative to positive or from positive to negative.
What does negative divided by a positive equal?
Rule 2: A positive number divided by a negative number equals a negative number. When you divide a negative number by a positive number, your answer is a negative number. As with multiplication, it doesn’t matter which order the positive and negative numbers are in, the answer is always a negative number.
How do you multiply positive and negative numbers?
Multiplying Positive and Negative Numbers When multiplying a positive number and a negative number (or a negative number and a positive number), multiply the absolute values, and give the answer a negative sign. 8 x -5 = |8| x |5| = 8 x 5 = 40, but give it the negative sign, making it -40 -13 x 3 = -39
How is a minus divided into a plus?
Answer Wiki. Well, now divide the first minus sign with the help of the second minus sign (or vice versa) into equal parts vertically.
Which is the correct way to divide a positive number?
Rule 1: A positive number divided by a positive number equals a positive number. This is the division you have been doing all along. For example: 16 / 4 = 4. We don’t place + in front of the numbers. It’s assumed no sign in front of the number means positive.
