An expression with numbers only is one that does not contain any variables (like xxx, yyy, or zzz). It consists entirely of numbers and operations.


Let's analyze the options:




  1. (7 × 20) – (5 × 10) – 45: This expression contains only numbers and arithmetic operations (multiplication and subtraction). It does not have any variables.



  2. 3x: This expression contains a variable xxx, so it is not an expression with numbers only.



  3. (7 × 20) – 8z: This expression contains a variable zzz, so it is not an expression with numbers only.



  4. 5 – 5n: This expression contains a variable nnn, so it is not an expression with numbers only.




Correct Answer:


1. (7 × 20) – (5 × 10) – 45
