What's the answer?

7

but google has the answer it must use scientific

There is a precedence given to arithmetic operators. Multiply and divide take precedence over add and subtract. So your scientific (so-called) calculator is correctly evaluating what would be better expressed as 1+(2*3)=7

(1+2)*3=9

VoG is right,logically. resistance is futile.

thought so, b.o.d.m.a.s. rule brackets over division,multiplication,addition subtraction

Try getting a calculator that uses REverse Polish Notation (Hewlett Packard used to make them). Then you can't go wrong.

2

Enter

3

Multiply

1

Plus

when i doubt give google a shout

it came up with 1+2*3=7

you guys are just confusing me now

;-)

Depends where you put the parenthesis(without VoG is right) with,could go either way.

Would have been better without the with.
