We have to evaluate the expression:
10 b + 3 c
for b = 3 and c = 11
So, we replace b and c by their respective values, and proceed to operate:
10 (3) + 3 (11) = 30 + 33 = 63
where the product 10 times 3 = 30, and the product 3 times 11 = 33
where completed BEFORE we add them, following the rules of mathematical operations.
