12a + a - 3a = 10a
Oh, what a happy little math question! When you multiply 3a by a, you simply multiply the coefficients (3 and 1) to get 3, and add the exponents (1+1) to get a^2. So, 3a multiplied by a is 3a^2. Just like painting, math can be a beautiful and calming experience when you take it step by step.
5a times 3a minus 8a = (5*3)*a2 - 8a = 15a2 - 8a
In math decrease means minus and increase means plus
238 minus 92 is 146. Simple math.
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.
5a times 3a minus 8a = (5*3)*a2 - 8a = 15a2 - 8a
7a-2b
a < -12
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
