How do u rewrite 37(3-z) without using grouping symbols

So I assumed you mean without parenthesis. To rewrite this expression, distribute the 37 to the 3 and -z, or in other words, multiply them. Then, add your two products.

37(3 - z)
(37 X (3)) + (37 X (-z))
111 + (-37z)

111 - 37z is your answer

Hope this helps!
