Evaluate: 6 - 6 squared divided by 3 12 divided by 6 + 15 divided by 3 - 2. Put pairs of?

Yes, you certainly are stuck. You have not learned how to write a math statement. That is fatal. There is no answer when you don't know what the question is.

6 - 6 squared divided by 3 ;; in standard presentation:

6 - 6^2 / 3 ;; this is ambiguous:

1) (6 - 6^2) / 3 = (6 - 36) / 3 = -30 / 3 = -10
2) 6 - ((6^2) / 3) = 6 - 12 = - 6
3) 6 - (6^(2 / 3)) = 6 - 3.301927... = 2.698072...
-------
12 divided by 6 + 15 divided by 3 - 2 ; I guess, this is supposed to mean
(12 / 6) + (15 / 3) - 2 = 2 + 5 - 2 = 5 ;; Parentheses (), or brackets [],
even curly braces {} help a lot to disambiguate
----------
Put pairs of brackets to make the equation true:
4 X 33 - 1 + 10 divided by 6 = 3.

4 X (33 - (1 + 10)) / 6 = 4 X 22 / 6 = 14.666... ;; that's as small as it gets by just putting parentheses in.
----------
3 + 2 X (3 + 2) = 3 + 2 X 3 + 2 X 2 = 6 + 4 + 3 = 13
or from the inside out
3 + 2 X (3 + 2) = 5 X 2 + 3 = 10 + 3 = 13

3 + 2 X (3+ 2 X ( 3 + 2 X ( 3 + 2))) = ;; from the inside out

3 + 2 = 5 ; times 2

2 X ( 3 + 2) = 10 ; plus 3

( 3 + 2 X ( 3 + 2)) = 13 ; times 2

2 X ( 3 + 2 X ( 3 + 2)) = 26 ; plus 3

(3+ 2 X ( 3 + 2 X ( 3 + 2))) = 29 ; times 2

2 X (3+ 2 X ( 3 + 2 X ( 3 + 2))) = 58 ; plus 3

3 + 2 X (3+ 2 X ( 3 + 2 X ( 3 + 2))) = 61.
