Parentheses

Exponent

Divide

Multiply

Add

Subtract

  1. 3 x 5 = 15; 5+15=20; 20-2=18
  2. 12/2 = 6; 6 x 6 = 36; 36+1  37
  3. 3^2=9; -9+6= -3; 4-3 = 1
  4. 8/2=4; 6 x 2 = 12; 12-4=8; 8+4 = 12
  5. (4+3)=7; -12-7=-19
  6. (4 x 3) = 12; 2(12)=24; 5 - 24 - 5 = 24
  7. (2)²=4; 5x4=20; 9 x 2 = 18; 18/6 = 3; 3-20= -17
  8. (-3)²=9; 9+1=10; 2-4=-2; -2/10= -1/5
  9. (2-5) = -3; (-3)²= 9; 2(9)=18; (4+18)= 22; 22-3= 19
  10. (½)²=¼; ¼ x ⅔ =2/12 = ⅙; ¾ - ⅙ = 7/12  

I hope it makes sense
