Simultaneous equations
A-B=14 (1)
AB=120 (2)
transposing(1) A=14+B
substituting into(2)
B(14+B)=120
B^2+14B =120
B^2+14B-120=0
solve quadratic
(B+20)(B-6)=0
B=-20,6
one of the whole numbers is 6 and the other is 6+14=20
Multiply them together
Multiplicand and Multiplier
The product of two whole numbers depends on what the numbers are. The operation is multiplication.11 and 8. You find the factors of 88 first. Then find which 2 will subtract to equal 3
first add the whole numbers then do simple fraction subtraction
You multiply them. Addition = sum Subtraction = difference Multiplication = product Division = quotient

six, nine 9 + 6 = 15 (sum) 9 - 6 = 3 (difference) 9 x 6 = 54 (product)
six, seven 7 + 6 = 13 (sum) 7 - 6 = 1 (difference) 7 x 6 = 42 (product)
12 & 3
The two numbers must be 6 and 9, as 6 + 9 = 15 and theer is a difference of 3 between 6 and 9. The product of 6 and 9 = 54.
