Question3×(4+5)(8+9)3 \times(4+5)-(8+9)

Studdy Solution

STEP 1

What is this asking? We need to figure out what this expression equals, respecting the order of operations! Watch out! Don't forget PEMDAS/BODMAS—Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
It's super important here!

STEP 2

1. Parentheses
2. Multiplication
3. Subtraction

STEP 3

Alright, let's **start** with the first set of parentheses: 4+54 + 5.
This gives us 4+5=94 + 5 = 9.
Easy peasy!

STEP 4

Next up, the second set of parentheses: 8+98 + 9.
Adding these together, we get 8+9=178 + 9 = 17.
Awesome!

STEP 5

Now, we've got 33 multiplied by the result we got from the first parentheses, which was **9**.
So, 39=273 \cdot 9 = 27.
We're cruising!

STEP 6

Finally, we **subtract** the result from the second parentheses (which was **17**) from the result of our multiplication (which was **27**).
This gives us 2717=1027 - 17 = 10.
And there we have it!

STEP 7

Our **final answer** is 1010!
