Dividing one negative integer and one positive integer results in a negative number: (12) / 3 4. Revise about how to multiply and divide indices, as well as apply negative and fractional rules of indices with this BBC Bitesize GCSE Maths Edexcel guide. Dividing two negatives or two positives yields a positive number: 12 / 3 4. Ignore the signs of the factors for now to make it easier to multiply. So the answer to that challenge problem is positive one. As with multiplication, the rules for dividing integers follow the same positive/negative guide. First, notice that the factors have different signs. If I pair my negatives up these two will pair up and become a positive and these two pair and become a positive so the answer is just a positive times a positive which a positive is. I have negative one times a negative one times a negative one. Negative times a positive is a negative so three times eight is twenty four and it will be negative. This simple Multiplying Negative Numbers game has been designed to help your child to practice their multiplication with a range of negative and positive. For scientific notation use 'e' notation like this: -3.5e8 or 4.7E-9. Integers, decimals or scientific notation. For negative numbers insert a leading negative or minus sign before your number, like this: -45 or -356.5. You can use: Positive or negative decimals. A positive needs a pair so the answer is negative so five times two is negative ten. Add, subtract, multiply and divide decimal numbers with this calculator. Learn to multiply and divide negative numbers. They have paired up and become a positive so negative four times five is positive twenty.

So now let’s go back and look at our example problems. So always think of negatives coming in pairs. A positive times a negative is a negative, and positive times a positive is a positive. So if you have negative times a positive the negative doesn’t have a pair therefore the answer is negative. An even number means that it is positive. An odd number of minus signs means that the answer is negative. Look at the number of minus or negative signs in the two numbers you're multiplying. For the example in the first step, place 3 over 4 to get 3/4. The way I think about it is that negatives always come in pairs so they pair up and become a positive. Place the result over the denominator, or bottom number of the fraction. Positive five times negative two is negative ten, and negative eight times positive three is equal to twenty four. Negative four times negative five is equal to positive twenty. Today we are talking multiplication of sign numbers, so here are our examples.
