If we start with just 2 2 the resulting answer 4.

Rules for multiplying positive and negative numbers. 3 4 1 2 3times412 3 4 1 2. The answer is -2 x -4 8. So thats another rule.

-2 x -4 are both negative so we know the answer is going to be positive. A negative number times a negative number equals a positive number. There are rules for multiplying integers and dividing integers which are very similar to the rule for addition and subtraction.

Add the absolute value of the numbers and keep the same sign. Negative Negative Negative. Positive positive Positive 4 5 9 negative negative Negative -4 -5 -9 DIFFERENT SIGNS- Subtract and Keep the Sign of the Bigger Number.

L-5 l 5 and l 5 l 5 ADDING INTEGERS SAME SIGN- Add and Keep the Sign. Rules for multiplying integers. So always think of negatives coming in pairs.

It is positive because the signs are the same. Two negatives make a positive so a negative number times a negative number makes a positive number. Multiply the numbers 93 and divide the numbers 18 9.

The number 9 has a positive sign while the number 3 has a negative sign. For each of these combinations lets talk about what happens when we multiply. Heres the overall rule to remember when multiplying positive.

When we multiply two. Multiplying these two numbers with different signs should output a negative answer. They have paired up and become a positive so negative four times five is positive twenty.

If the signs are different subtract the numbers and use the sign of the larger number. The rule for multiplying and dividing is very similar to the rule for adding and subtracting. To multiply integers use your multiplication table skills to multiply the numbers.

-5 -4 -9. A positive times a negative is a negative and positive times a positive is a positive. So now lets go back and look at our example problems.

6 5 11 6 and 5 are both positive. Therefore when we multiply a positive number by a negative number the answer is negative. We may have positive and negative integer values when working with integers in multiplication.

Adding and multiplying combinations of positive and negative numbers can cause confusion and so. It seems like multiplication and division would be more complicated than addition and subtraction but theyre actually much simpler. If you look at it on the number line walking backwards while facing in the negative direction you move in the positive direction.

10 x 9 90 -10 x -9 90. To determine the sign of the answer. 4 7 11.

Positive Positive Positive. The rules are a negative times negative is equal to a positive. But here we have a negative times a positive 2 and it turns out that when you multiply a negative times a positive you get a negative.

Positive 6 plus Negative 3 equals Positive 3 We could write it as 6 3 3. If the signs are the same the answer is. The rule for multiplying positive and negative numbers with the same sign two positive or two negative is that the product will always be positive.

When the signs are different the answer is negative. Count the number of negative signs if you have an even number of negatives the result is positive but if you have an odd number of negatives the result is negative. As it doesnt matter which way round you multiply the numbers we can also say that if we multiply a negative number by a positive number then the answer is negative.

8 8. -2 x -4 are both negative so we know the answer is going to be positive. This problem has just one negative sign.

-5 -3 -8 Basically add the numbers and put back the negative sign Sum of a negative and positive number. If the signs are different the answer is negative. When adding numbers of the same sign either positive or negative add their absolute values and give the result the same sign.

Dividing 18 9. If we take that 4 and times is by the final 2 4 2 is 8 as a negative multiplied by a positive results in a negative answer. What does a Times and a minus make.

6 5 is 11 which is positive -7 -8 -15. Negative times positive is equal to negative. 8 x 4 32 -8 x -4 32.

1 0 1 1 0 10times110 1 0 1 1 0. In short when multiplying if the two signs are different then the answer is negative. If the multiplied numbers have the same sign positive or negative the answer is always positive.

The number 9 is positive while 3 is negative. When multiplying and dividing more than two positive and negative numbers use the Even-Odd Rule. The numbers 3 and 6 have the same sign positive so their multiplication is positive.
