Question

Which expression is undefined?
A) (-7 - 0)
B) 7/0
C) -0/2 ÷ 10
D) (4 - 4)

Answer 1

The expression 7/0 is undefined because division by zero is not allowed in mathematics, as it does not yield a meaningful result.

Step-by-step explanation:

The expression that is undefined out of the options provided is B) 7/0. Division by zero is undefined in mathematics because there is no number that you can multiply by zero to get a non-zero number. Therefore, when you try to divide by zero, it does not give you a meaningful result. The expressions A) (-7 - 0), C) -0/2 ÷ 10, and D) (4 - 4) all result in defined values: -7, 0, and 0 respectively.The expression that is undefined is B) 7/0. Division by zero is undefined in mathematics because there is no number that can be multiplied by zero to give a non-zero value. In this case, dividing 7 by 0 would result in an undefined value.
