If a = 24 and b = 6, then a - b = 24 - 6 = 18

a=7 b=9 ab=? ab is the multiplication of a & b there fore the value of ab=7*9=63
AB/8Cas divided by 8/A can be reversed to multiplied by A/8so B/C x A/8 = AB/8CExample: If A=4 B=6 C=3then 6/3 divided by 8/4 = 2/2 = 1also AB/8C = 24/24 = 1Q.E.D.

If a = 24 and b = -6 then 24--6 = 30 because --6 = +6

30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
ab means that a is multiplied (times) by b and then 6 is subtracted from the answer. So if the question says "If a = 5 and b = 4, what does ab - 6 =?" then you multiply 5 x 4 = 20 and subtract 6. So the answer is 14.
so let's group and then factor ab+2a+3b+6= (ab+2a)+(3b+6)= a(b+2)+3(b+2)= (a+3)(b+2) and that is our final answer! Doctor Chuck
