1000+50-36+7×9+8÷5×2+1​
melomori [17]

Answer:

949.2

Step-by-step explanation:

To solve this equation, you must use P.E.M.D.A.S...

First, solve 7x9 and 5x2...

7x9= 63  5x2 = 10

So...

1000+50-36+63+8÷10+1

Next, solve 8÷10 and get 0.8

So...

1000+50-36+63+0.8+1

Then, solve 1000 + 50, and 36+63, and that result with 0.8 and that with 1.

So...

1050-100.8

The Solve!

949.2

Hope this helps!
