Worked Example: Translating Words to Algebra
Write these in algebraic notation:
a) "5 times a number x"
b) "a number y, multiplied by itself"
c) "3 less than twice a number n"
Part a "5 times a number x"
5 times x means 5 × x
In algebra we write this as: 5x
Part b "a number y, multiplied by itself"
y multiplied by itself means y × y
In algebra we use powers: y²
Part c "3 less than twice a number n"
"Twice n" means 2 × n = 2n
"3 less than" means subtract 3
Answer: 2n − 3
