Hello, cheliciouspie!

\(\displaystyle \text{Evaluate: }\:6-1\cdot0+2 \div 2\)

Don't you know the "Order of Operations"?

Do all the multiplication and division before any addition and subtraction.

So we have: .\(\displaystyle 6 - (1\cdot0) + (2\div 2)\)

. . . . . . . . \(\displaystyle =\;6 - 0 + 1\)

. . . . . . . . \(\displaystyle =\;7\)

@markfl2 and @Soroban

Thanks for your replies...

i know the order of operation... (MDAS).. My answer as well is 7... but i'm just confuse cause my friends told me that it's 5.

they say 6-0+1 = 5....that is 6-(0+1)=6-1=5...

They told me that addition first before subtraction...

Addition and subtraction are done at the same level from left to right. You are right and your friends are not.
