Simplify the following expressing. Show your work and explain each step. <br><br> 7-(5-3(2+6(2^2)))
Anon25 [30]

Answer:

80

Step-by-step explanation:

7-(5-3(2+6(2^2)))

When a question has multiple signs, the rule of BODMAS is used. That is, Bracket Of Division Multiplication Addition and Subtraction. The question above will therefore be solved in that order.

The first bracket, we have 2^2

That gives 4

Rewriting the question will give

7-(5-3(2+6(4)))

The question in the next bracket will follow

(2+6(4))

In this bracket too, we have the plus sign and the multiplication sign, so the multiplication will first be solved, them addition will follow.

(2+24)

(26)

Rewriting the question again, we have

7-(5-3(26))

And then, we have the last bracket

(5-3(26))

But we have both the Subtraction sign and the Multiplication sign in this bracket also, so the multiplication will first be solved, before the Subtraction.

(5-3(26))

(5-78)

(-73)

And lastly we have

7-(-73)

7+73

A pitcher of fruit punch holes 2 gallons of nine people share the entire pitcher equally how much punch does each person get?
Katen [24]
Well, first you must divide the amount of gallons by the amount of people.
2/9 = 2/9 gallons which would be about 3.5 cups.

(Personally I would do 2/9 cups)
