In mathematics, the order of operations dictates that you perform addition and subtraction in the order they appear from left to right in an expression. This means that you should perform addition before subtraction only if addition comes before subtraction in the expression. If addition and subtraction are next to each other, you would perform them from left to right.

it means to subtract
The denominators must be the same before you can add or subtract fractions.
deposit = add withdraw = subtract
because it would be diffcult to understand.[you don't add or subtract the demonters]
wich one
So that you only have to add/subtract the numerator which makes it much easier.
does how many mean add or subtract
The opposite of add is subtract.
Before you can add or subtract fractions, the denominators must be the same. If the denominators are different, you need to find a common denominator by determining the least common multiple of the existing denominators. Once the denominators are equal, you can add or subtract the numerators while keeping the common denominator.
it means to subtract
No, the denominators have to be the same.
The denominators must be the same before you can add or subtract fractions.
deposit = add withdraw = subtract
To get the number before a number, subtract one. To get the number after the number, add one.
You add or subtract only the numerators
