# Rational numbers

## How to

to add integers all you need to do is find the absolute values and add them. You keep the sign of the greater absolute value.

To subtract all you need to do is keep change change. Then follow the rules for adding.

To multiply find the absolute values and multiply. If there are a odd number of negatives the product will be negative.

To divide find the absolute values then divide normally. If there is an odd number of negatives the quotient is going to be negative.

comparing and ordering is easy the greater number is all ways a positive so make sure you facing away from negatives. If both are positive the one that's absolute value is farther from zero is the greater.

Here are some examples of real life problems:

Bill has 102.30 in his banking account he buys a pair of jeans for 56.28. how much money does he have left? the answer 46.02 dollars

Joe needs to buy 234.00 $ worth of grocery to have enough food for the week he gets paid 300$ a week but has to pay taxes and bill and is left with 98$ will he have enough money to buy grocery after 2 weeks? Yes

Will has to pay rent which is 500$ a month he and his roommate makes a total of 720$ in total they work at the same place and get payed the same amount. How much do they make and could one person pay the rent alone? They each make 360$ so no they have to live together to be able to pay the rent.

My numbers are:

0.56

-3

4

-2\-16

here the rest:

-3<-2/-16

.56+|-3|= 3.56

|-3|+|4|= 7

4+|.56|= 4.56

|-2\-16|+|4|= 4 2/16

THe absolute value is just the distance an integer is away from zero.
