Why is it important to know the order of operations as a mathematician?

So everyone can solve every problem the same (correct) way.

True or Fale: 5²=10

False. 5²=25

The problem was 20 - 5 x 2 + 3. My answer was 33. What did I do wrong?

I went from left to right without using the correct order of operations.

Fix my Mistake

100

9 - 3 x 2=12

Correct answer is 3. Do x then -, not - then x.

200

5 ² + 1=11

5 ² = 25, not 10. Correct Answer is 26.

300

3² - 6 = 0

3 ² = 9, not 6. Correct answer is 3

400

4 + 5 + 7 - 3 x 2 = 26

You need to follow PEMDAS and do x first. Correct answer is 10.

500

10 ³ = 30

10 ³ = 10 x 10 x10, which is 1000, not 30.

Q1 (+,+)

Q2 (-,+)

Q3 (-,-)

Q4 (+,-)

True or false: it does not matter which operation you solve first when it comes to division and multiplication because they are equal in power.

False: although they are equal in power, you would solve them left to right
