How can knowing that multiplication is repeated addition and division is repeated subtraction help you understand that multiplication and division are related?
the whole reason is this: multiplication is adding to that number in groups and division is subtracting from a number in groups.
Why is it better to rewrite subtraction into addition?
It can help SOME people to understand it better - though others find it makes things more confusing. So it is NOT universally better.
How are addition properties and subtraction rules helpful when solving problems?
I need help, Please help me and others out
How is regrouping and subtraction difference from regrouping addition?
I need help with that. I happen to have that question now in my Math lesson :( HELP!!!
Why it happens in maths that addition and subtraction makes subtraction?
Ok i can see where you would have trouble with this. When i first started Algebra, i wasn't quite sure how this worked. Here are some examples: 2-+2=0 the subtraction sign cancels the addition out. (2-2 is the same thing) 2- -2= 4 the two subtraction signs make an addition sign. (2+2 is the same thing) I hope i could help you.
