Let's say a is 1, and b is 2. Is 1-2 the same as 2-1? I didn't think so. This is because subtraction is the same thing as adding a negative number, so by switching the a and b, you are also switching them between negatives and positives. However, -a-b is the same as -b-a.
The expression is: ab-18
It is: ab+10
(a-b)(a^2 + ab + b^2)
Using the communative property of both addition and multiplication, 11+ab could be rewritten as ab+11, 11+ba or ba+11.
a ⊕ b = ab' + a'b
The expression is: ab-18
ab increased by 2
11 + ab is the expression.
Yes, because there is no equal sign. Having an equal sign would make it an equation.
It is: ab+10
(a-b)(a^2 + ab + b^2)
Here are some rules that can help you simplify such expressions, in some cases. (ab)c=abc abac = ab+c ab/ac = ab-c
ab + 2
Equation, not expression. A and B are two numbers. (A + B)2 = A2 + B2 + 2(AB) ----------------------------------
a times b
Using the communative property of both addition and multiplication, 11+ab could be rewritten as ab+11, 11+ba or ba+11.
Plus ab is an algebraic expression. As given you cannot solve it. However, If you have x +ab = c Then 'ab' can be solved. We do this by subtracting 'x' from both sides. (Preserve equality) x - x + ab = c - x x-x = 0 , just like 2 - 2 = 0 Hence ab = c -x
