Answer:
1
Step-by-step explanation:
Because 2 times 1 is 2 plus 1 is equal to 3
It's actually PEMDAS. P is for parenthesis. E is for exponents. M is for multiplication. D is for division. A is for Addition. S is for subtraction.
Here's an example that includes all of these:
(6-2)²x4/2+6-4
P first.
(6-2) = 4
(4)²x4/2+6-4
Now E.
(4)² = 16
16x4/2+6-4
Then M.
16x4 = 64
64/2+6-4
Next is D.
64/2 = 32
32+6-4
Now A.
32+6 = 38
38-4
And finally, S.
38-4 = 34.
I hope this helped
