Answer:
-10.
Step-by-step explanation:
Step 1: Explain/define
This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.
P (Parenthesis)
E (Exponents)
M/D (Multiplication/division, whichever comes first)
A/S (Addition/subtraction, whichever comes first)
This is the correct sequence of steps when solving expressions with multiple operations.
PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."
------------------------------------------------------------
Step 2: Solve.
REMEMBER PEMDAS!
Expression given: 4 × 3 + 2 × 9 - 40
There are no parentheses.
There are no exponents.
There is multiplication, but no division.
4 × 3 + 2 × 9 - 40
12 + 18 - 40
There is addition and subtraction. Remember to solve whichever comes first.
12 + 18 - 40
30 - 40
30 - 40 = -10.
I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.
