Fascinating Fact:

These puzzles are linked to algebra because both use symbols to stand for unknown values.

In 11 Plus Verbal Reasoning, letters for numbers puzzles require pupils to connect symbols with values. They build reasoning skills, improve working memory, and prepare pupils for complex problem solving in exams.

  • Symbol: A sign, such as a letter, used to represent another value like a number.
  • Substitution: Replacing one item, such as a letter, with another, like a number.
  • Reasoning: The logical process of working out a solution step by step.
What are letters for numbers puzzles in the 11 Plus?

They are reasoning puzzles where letters represent numbers. Pupils must work out the hidden rule and apply it to complete the sequence or solve the problem.

Why are letters for numbers puzzles useful?

They help pupils practise logical thinking and memory skills. These abilities are important for success in verbal reasoning and across other school subjects.

How can I practise letters for numbers questions?

Pupils can practise using sample quizzes and exam-style questions. Starting with easier puzzles and moving to harder ones builds confidence and speed.

Example: What is the answer to the sum below, written as a letter?
A = 5, B = 14, C = 12, D = 13, E = 3
A + C - E = ?

A
B
C
E

Answer: The correct answer is B. If we translate all the letters into numbers, our new sum is 5 + 12 - 3, which = 14. 14 = B.
1 .
What is the answer to the sum, written as a letter?

D = 9, T = 18, N = 6, Z = 3
D + N - Z + N
D
T
N
Z
If we translate all the letters into numbers, our new sum is 9 + 6 - 3 + 6, which = 18. 18 = T. Interesting number alert! 9 is a square number
2 .
What is the answer to the sum, written as a letter?

B = 6, C = 12, R = 18, V = 2
C x V - B
B
C
R
V
If we translate all the letters into numbers, our new sum is 12 x 2 - 6, which = 18. 18 = R
3 .
What is the answer to the sum, written as a letter?

F = 7, W = 6, O = 12, R = 4
F - W + R + F
F
W
O
R
If we translate all the letters into numbers, our new sum is 7 - 6 + 4 + 7, which = 12. 12 = O. Interesting number alert! 7 is a funny number. If we look at the factors from 7, they add up to interesting numbers: 2 x 7 = 14 (adding up to 5) 3 x 7 = 21 (adding up to 3) 4 x 7 = 28 (adding up to 10 as well as 1 + 0 = 1) 5 x 7 = 35 (adding up to 8) 6 x 7 = 42 (adding up to 6). Can you guess what comes next? It always equals two less than the number before it
4 .
What is the answer to the sum, written as a letter?

H = 16, S = 14, M = 12, P = 2
H + M ÷ P
H
S
M
P
If we translate all the letters into numbers, our new sum is 16 + 12 ÷ 2 , which = 14. 14 = S. Interesting number alert! 16 is a square number (4 x 4)
5 .
What is the answer to the sum, written as a letter?

C = 31, G = 1, Q = 8, J = 4
C + G ÷ Q + J
C
G
J
Q
If we translate all the letters into numbers, our new sum is 31 + 1 ÷ 8 + 4, which = 8. 8 = Q. Interesting number alert! 31 is a prime number
6 .
What is the answer to the sum, written as a letter?

E = 5, M = 12, D = 4, C = 1
M - E + D + C
E
M
D
C
If we translate all the letters into numbers, our new sum is 12 - 5 + 4 + 1, which = 12. 12 = M. Interesting number alert! 12 is a number where, if you add up the numbers it is made of, it equals 3. Double it and add those numbers (24 gives us 6) and it equals three more than the first two numbers added up to. No matter which factor you use, this works. Try it!
7 .
What is the answer to the sum, written as a letter?

A = 30, D = 25, C = 65, B = 3
A x B - C
A
D
C
B
If we translate all the letters into numbers, our new sum is 30 x 3 - 65, which = 25. 25 = D
8 .
What is the answer to the sum, written as a letter?

F = 9, X = 17, G = 4, K = 2
X - F ÷ G + K
X
F
G
K
If we translate all the letters into numbers, our new sum is 17 - 9 ÷ 4 + 2, which = 4. 4 = G. Interesting number alert! 17 is a prime number!
9 .
What is the answer to the sum, written as a letter?

R = 81, S = 9, T = 10, U = 1
R ÷ S + U ÷ T
R
S
U
T
If we translate all the letters into numbers, our new sum is 81 ÷ 9 + 1 ÷ 10, which = 1. 1 = U. Interesting number alert! 81 is not only a square number (9 x 9) but its two numbers also add up to 9!
10 .
What is the answer to the sum, written as a letter?

J= 13, Q = 9, D = 23, P = 117
J x Q - P + D
J
Q
P
D
If we translate all the letters into numbers, our new sum is 13 x 9 - 117 + 23, which = 23. 23 = D
