Let’s go step by step through each problem. We’re turning word phrases into math expressions — that means using numbers, letters (variables), and operation signs like +, –, ×, ÷, or exponents.
---
1. 12 more than x
“More than” means addition. So we add 12 to x →
x + 12
2. x less than 36
“Less than” means subtraction, but note: “x less than 36” means start with 36 and subtract x →
36 – x
3. one-third of a
“One-third of” means multiply by 1/3 →
(1/3)a or
a/3
4. 17 times s
“Times” means multiplication →
17s
5. b multiplied by 5
Same as above →
5b
6. y to the fourth power
That means y raised to exponent 4 →
y⁴
7. 64 plus k
“Plus” = addition →
64 + k
8. u tripled
“Tripled” means multiplied by 3 →
3u
9. p cubed
“Cubed” means to the third power →
p³
10. 18 minus x
Straightforward subtraction →
18 – x
11. 4 less than k
Again, “less than” reverses order: start with k, subtract 4 →
k – 4
12. z increased by 12
“Increase by” = add →
z + 12

Now for questions 13–19:
13. What is the product of 82 and g?
“Product” = multiplication →
82g
14. What is the difference between n and 7?
“Difference” = subtraction. Usually it’s first minus second unless specified →
n – 7
15. What is the quotient of 32 and x?
“Quotient” = division →
32 ÷ x or
32/x
16. What is the sum of h and 7?
“Sum” = addition →
h + 7
17. What is 31 less than c?
Start with c, subtract 31 →
c – 31
18. What is the fifth power of t?
t to the 5th power →
t
19. What is one-eighth of r?
Multiply r by 1/8 →
(1/8)r or
r/8
