The order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction), should be followed when solving mathematical expressions. In this case, we have:
[42 ÷ (-2)] ÷ (-7)
First, we need to solve the expression inside the parentheses, which is a division operation. 42 divided by -2 equals -21:
[-21] ÷ (-7)
Next, we need to solve the division between -21 and -7, which gives us a result of 3:
-21 ÷ -7 = 3
Therefore, the solution to the expression [42 ÷ (-2)] ÷ (-7) is 3.

Answer:
42 ÷ (-2) = -21
Now the expression becomes:
(-21) ÷ (-7)
(-21) ÷ (-7)
= 3
Therefore, [42 ÷ (-2)] ÷ (-7) = 3.

A negative number divided by a positive number will give us a negative number.
Two negative numbers divided will be equal to a positive number.
[42 ÷ (-2)] ÷ (-7) =
= (-21) ÷ (-7) =
= 3
Hope that helps! Good luck! :)
