2. The quotient of fifteen and three subtracted from the product of four and nine.
3.The difference between twenty and five multiplied by the sum of eight and two.
4.Three times the square root of the sum of nine and seven.

Ms. Sue,
I'll get you started.
1.
2(25 + 8)
2.
(4 * 9)  (15/3)
I'll be glad to check your answers to the other two problems.

3.
(205)*8+2
4.(7+9)3
Is this correct? I seem to be struggling with this for some reason.

Ms. Sue,
3. Good  except it would be clearer if you put parentheses around 8 + 2
(205)*(8+2)
4. You didn't use the square root symbol. Let's see if I can do it.
3 √ (9 + 7)
