What is 41?
5 3 using exponent means
It means 5 x 5 x 5 which equals to 125.
4 + 5 + 7 - 3 x 2
26
You need to follow PEMDAS and do x first. Correct answer is 10.
20 – (5+3) x 2 + 4 + 0.5
What is 8.5?
7+ (5+ 1) X 9
What is 61?
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. Answer is 13.
10 3 = 30
10 3 = 10 x 10 x10, which is 1000, not 30.
(5 x 4) – 6 ÷ 2 + 9 + 3/4
What is 26 3/4 or 26.75?
