What are numerical expressions that are equal or algebraic expressions that are equal for all values of the variable?
483h4yg3h45
Which of these is a numerical expression?
None of the expressions on that list is a numerical one.
Is 3 plus 7 a numerical expression?
Yes. Anything which you can evaluate (calculate) to get a number is a numerical expression. Thus, all of the following are numerical expressions:5x (if the variable stands for a number)1 + 25 / 3square root of (5 / 3)In general:* Any number* Any variable that stands for a number* An addition, subtraction, multiplication, division, or power that involves numerical expressions is again a numerical expression (as long as the operation makes sense - for example, you can't divide by zero)* Many mathematical functions, with a numerical expression as a parameter - for example, sin(5 + 3), ln(10), etc.
Can numerical expressions have the same value?
Yes, numerical expressions can have the same value. For example, the expressions 2+3 and 5 both have the value of 5. Similarly, the expressions 2x3 and 6 both have the value of 6. In general, any two numerical expressions that evaluate to the same number will have the same value.
What does numerical expressions mean?
A Numerical Expression is an expression only using numbers.
