I need help I can't add + subtract
Ok here is my problem, I am becoming a assistant manager at my job which require me to count money. Which means I need to know how to add + subtract. Now I can count the only deal is when some one asks like 20-7 any questions like that I have to use a calculator are even 100-22, I can't respond. Now I was in resource math in elementary thats why I am not to good at math. So what do I need to know to be able to add and subtract and respond right away.

well its not too hard. ok so imagine someone asks you to subtract 22 from 100. OK so you allready have 100, and need to take away 22.
how about 100-20=80 80-2=78
so you could break it up, OR you realise that its lest than 30 and more than 20, so take away 30 from 100. 30 is too much though, and we add on on 8. quite simple if you get your head around it..practice makes perfect...:D

Ohh, this MAY sound stupid, but the best thing that you could do, is go on a maths website and just practice it.
It's nothing to worry about!
Just practice on the websites and practice whenever you can ( doing things in your head) and you will becmoe better and better.
Also another thing that helps is if you go to the super market try to add the prices of things you buy.
This is the best method.
Hope it helps!
