Answer:
i.1832 ii.-56
Step-by-step explanation:
using BODMAS for the first question we solve for what's in the bracket after we go with the division and after multiplication next addition and subtract in doing all that we get
35+25*72-51/17
35+25*72-3
35+1800-3
1835-3
1832
you can also use your calculator to verify answer
ii.-6*9+7-4-5
-54+7-4-5
-47-4-5
-56
