Question

Which of the following is a numerical expression

A. x+y
B. 2b -5
C. 6 x 4
D. 425

Answer 1

2b -5 is a numerical expression

Answer 2

A numerical expression is one that has no variables, just numbers. You can see that choices A and B both have variables, so they can't be the answer. 425 isn't an expression, it's just a number, so the answer is C. 6 x 4 .
