Please help me:) For problems 13-19, transcribe the following expressions: (Write it out.)

Example: z + 4 = z plus 4
13. xy
14. 7/t - 4
15. 22 + t 2
16. 51 - x
17. x – y^2
18. 36/12 + 12
19. ab - 16

13. xy= x times by y
14. 7/t-4= 7 divided by t take away 4
15. 22+t 2= 22 add t squared
16. 51-x= 51 take away x
17. x-y^2= x take away y squared
18. 36/12+12= 36 divided by 12 add 12
19. ab-16= a times by b take away 16

If this is what it means , I hope this helped ! :)
