It equals 4.7 but is commonly rounded up
b + a + b - a = 2b
the answer is a
b+b+b+b+b is equal to 5b. That is because there are five b's being added up. 1+1+1+1+1 is 5 because there are five 1's being added up.
If the question is, "What is b if b + 24 = 19 ?", then : b + 24 = 19 b = 19 - 24 = -5
It is B+a+5
2b
If a = 2b
-50
-13
(a+b)(a+b)Also equal to a2+2ab+b2
If you do not assume that "plus" is commutative, all that can be said that it is equal to A plus B.
