I know how its done!

Remember, PEMDAS

Do the exponent first.

[tex]21/7+20*100*2-3[/tex]

Then you have to do Multiplication And division from left to right.

21/7=3
20*100=2000
2000*2=4000

3+4000-3

Last do Addition and subtraction from left to right.

3+4000=4003
4003-3=4000

Answer is 4000

Hope that helps! And I hope I did it in time.
