Answer: =20 *The answer should be positive sign.*

Step-by-step explanation:

This question it's about PEMDAS. This lesson it's about order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.

do multiply first left to right.

2*0=0

3+16-0+1

add/subtract left to right.

3+16=19

19-0+1

19-0=19

19+1

19+1=20

=20

Hope this helps!

Thanks!

Have a great day!
