A+c= 2a+b
a=24 b=16 c=18
ab=1a+1b a is equal to either 0 or two, and b is equal to a
If 'A' and 'B' are vectors, and their magnitudes are equal, andtheir directions are opposite, then their vector sum is zero.
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.
