When multiplying by 1, this also does nothing to a number and just leaves it the same however, this is not the case when multiplying by 0. Clearly, when adding or subtracting 1 we simply move one number up or down, but adding or subtracting 0 does nothing. ![]() Using 0 and 1Īnother basic skill which you will need to learn is what happens when we use 0 and 1 in our manipulation of numbers. nope negative plus negative equals a negative -2+ (-4)-6 but negative times negative equals a positive. Negative greater than positive equals negative. These are the fundamental calculations between numbers and you should make sure that you know these very well.įor your exam you will need to purchase a scientific calculator and it is recommended that you read through the instructions when you purchase the calculator so that you know how to perform these basic operations. Positive greater than negative equals positive. Negative multiplied by Negative is a positive number, which means that the product of two negative integers is. We can use the same rule when we divide positive and negative numbers: Example: 2 × 5 10 (We already discussed that when a number doesnt have a sign, it usually means its positive.) (Image will be uploaded soon) Minus Multiply Minus is Plus. If you have an even, if you have an even number of negative, well then the whole thing is going to be, the whole thing is going to be positive. This is the pattern for all numbers when multiplying: If you have an odd number of negative numbers in your product or in your quotient, well then youre going to have a negative, youre going to have a negative value for the entire expression. There is clearly a rule which we can follow here: that whenever we have two negatives we can replace them with a plus. ![]() When we multiply two negative numbers, we again get a positive. Or we could say that ‘two minuses make a plus’. In other words, subtracting a negative number is the same as adding that same number. In the previous section we looked at adding and subtracting numbers using a number line, but what if we now decided to subtract a negative number? You may be able to work out that when doing this you move up the number line. From everyday life you should already understand positive and negative numbers, however, you may not understand the way in which we can manipulate these numbers. As we saw in the introduction to the chapter, negative numbers have a rich and storied history. ![]()
