Basic Algebra Rules
a+b c = a c + b c but a b+c 6= a b + a c (b) Cancellation of the c here requires that it appears in each additive term of the numerator and denominator: ca+cb cd = c(a+b) cd = a+b d but ca+b cd 6= a+b d (c) Compound fractions can be simpli?ed by using the rule “division is the same as multiplication by the reciprocal”: a b c d = a b ÷ c

What is a B B and C in math?
A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form?
What is the formula for a/B/C/D?
In the expression A/B/C/D, operations are done from left to right, so (A/B) is divided by C, yielding A/ (BC) and then this result is divided by D, yielding A/ (BCD). Of course, if the questioner was trying to get (A/B) / (C/D), we would end up with (AD)/ (BC).
What is ABCD in math?
ABCD is a rectangle. E, F, G and H are mid - point of sides AB, BC, CD and DA respectively. If ar (EFGH)= 16 cm2, find ar (ABCD). Find Math textbook solutions?
What is the fraction of a/B/C/D?
To simplify the fraction in the form of A/B/C/D, find the LCD, which is BD and multiply it to A/B and C/D to get (ABD/B)/ (CBD/D) which is equal to AD/CB. A fraction of the form A/B/C/D is basically nothing but A/ (B*C*D). Just multiply B, C and D together and divide A by the result obtained.
