According to the order of operations, addition and subtraction are on the same level and, therefore, must be resolved from left to right.
However, in the exercise we can use the substitution property to make solving simpler.
-5+4+1-3
4+1-5-3
5-5-3
0-3
-3
What is the result of the following equation?
\( 36-4\div2 \)
While it might work for this problem, it violates the order of operations. Mathematics requires us to follow rules consistently. Addition and subtraction have equal priority, so we must work left to right.
Think of it like reading! Just like you read words from left to right, you solve addition and subtraction from left to right. Start with the first two numbers, get their result, then continue.
Yes! You can use the substitution property to rearrange terms: . But make sure you understand the left-to-right rule first!
Work through the problem step-by-step again, or try the rearrangement method as a check. Both should give you -3 for this problem.
They're the same! and . Adding a positive number is the same as subtracting its opposite.
