Chris asks…

## how do you add,subtract, multiply and divide negative and positive decimal numbers? would you like to ask?

### The Expert answers:

Adding and Subtracting:

Lets have an example: 12.63+(-32.46)

first you have to line it up so that the decimal is in the same place

12.63

+-32.46

then you realize that adding a negative number is the same as subtracting a positive one

12.63

-32.46

Then you realize that this will end up a negative number, so you switch the numbers, with the intention of just making the number you come out with negative

32.46

-12.63

then you start at the end

6-3=3

4-6

you need to carry

14-6=8

remember you carried

1-2

you need to carry again

11-2=9

remember you carried

2-1=1

don’t forget to bring down the decimal

19.83

remember you switched the numbers, so make it negative

-19.83

Multiplication:

When multiplying, you are just going to forget about the decimals

example:

1.6*2.1

16

x 21

1*16=16

2*16=32

don’t forget that you need to add the place holders

16

+320

336

now you can put in the decimal

count the decimal numbers (all digits coming after the decimal point in both numbers)

there are 2, so count 2 places

its 3.36

remember, if one number is negative, make the answer negative

if both are either negative OR positive, make the answer positive

Division:

if the divisor has decimal numbers, multiply both the divisor and the dividend by 10 to the power of how many decimal numbers it has (10^2=100, and so on)

example: 15/2.5

multiply both by 10

150/25

its now a regular problem

if the dividend is a decimal, just bring it up

example 12.5/5

just do it ignoring the decimal

25

now bring up the decimal

2.5(I could show you better on paper)

I hope this helps
