12a + a - 3a = 10a
Oh, dude, you're hitting me with some math here. So, when you multiply 3a by a, you're basically multiplying 3 times a times a. That gives you 3a^2. It's like math, but with letters instead of numbers. Cool, right?
In math decrease means minus and increase means plus
238 minus 92 is 146. Simple math.
Thirty seven minus five is thirty two. Learning primary math functions such as addition and subtraction will make learning higher levels of math easier. Math can be a lot of fun.
3a + 5b - 6a - 9b = -3a - 4b
12a + a - 3a = 10a
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
3a - 2b
It is an algabraic expession without knowing whether or not 2b and 3a are plus or minus
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2

A plus with a minus under it means "plus or minus" in math.
7a-2b
a < -12
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
If your problem looks like this: 4a-a=_ the answer is... 3a
