A and B are single-digit numbers.
C is in the tens column.
D is in the 50s row and in the column that ends in 3.
E is in the 90s row and in the column that ends in 5.
This helps us to get the correct match:
A | = | 4 |
B | = | 8 |
C | = | 20 |
D | = | 53 |
E | = | 95 |
Let's have a go at some questions now.
