Can anyone help me for 13 points?:/

1. 150. Do 20*5 first, as it's in parentheses, then multiply by 10.
2. 36. Same thing as #1 but different numbers.
3. 51. Do the stuff in parentheses first, then multiply because it gets priority over subtraction and then subtract.
4. 16. Do the multiplication in the parentheses first, then the subtraction, and then the division.
