What is a negative times a negative integer?

What is a negative times a negative integer?

Rule 3: A negative number times a negative number, equals a positive number. Two negatives make a positive, so a negative number times a negative number makes a positive number. If you look at it on the number line, walking backwards while facing in the negative direction, you move in the positive direction.

What is the rule for negative integers?

RULE 1: The quotient of a positive integer and a negative integer is negative. RULE 2: The quotient of two positive integers is positive. RULE 3: The quotient of two negative integers is positive. If the signs are different the answer is negative.

What happens when we multiply 2 negative integers?

When you multiply two negative numbers or two positive numbers then the product is always positive. Since there is one positive and one negative number, the product is negative 12. (−3)⋅(−4)=12. Now we have two negative numbers, so the result is positive.

How do you explain a negative times a negative?

Multiplying by a negative is repeated subtraction. When we multiply a negative number times a negative number, we are getting less negative. This analogy between multiplication and addition and subtraction helps students nicely connect the two concepts.

Why does a negative times a negative equal a positive?

Explanation: We know that negative times anything means that it will change the sign. Ideally, the second negative should change the sign of our original number (which is also negative). So, our original negative sign is changed into a positive sign when a negative is multiplied to it.

Why is a negative times a negative a positive number?

If multiplication by a negative is a reflection across 0 on the number line, and we think of negative numbers as being reflections across 0 of the number line, then multiplication of a negative number times a negative number is a double-reflection.

What does a negative minus a negative equal?

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, – (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 – –4.

How does a negative times a negative equal a positive?

What is a negative minus a negative?

A negative minus a negative is equal to another negative number, a positive number or zero, depending upon the numbers in the equation. Subtracting a negative number from another negative number is the same thing as adding a positive number.

What does the negative sign mean in math?

“−” is the negative sign. If a number has no sign it usually means that it is a positive number. Let us think about numbers as balloons (positive) and weights (negative): Adding positive numbers is just simple addition. Subtracting positive numbers is just simple subtraction. Now let’s see what adding and subtracting negative numbers looks like:

What is the difference between positive and negative numbers?

Numbers less than zero are referred to as negative numbers. Numbers above zero are positive numbers. There are rules for adding, subtracting, multiplying, or dividing positive and negative numbers. We know that “+” is a positive sign, “−” is a negative sign. When a sign is not denoted before a number, it usually means it’s positive.

What are the rules for multiplying negative numbers?

Rules for Multiplying Negatives 1 Plus Times Plus is Plus. (We already discussed that when a number doesn’t have a sign, it usually means it’s positive.) 2 Minus Multiply Minus is Plus. 3 Plus Times Minus is Minus. 4 Minus Times Plus is Minus. 5 Division of Negative Numbers. 6 Solved Examples. 7 Conclusion.
