What's 5 + 1 x 10? Clue: If you get anything other than 15, it's wrong. Plain wrong. And it's not how we calculate transfer fees.

My answer was Boris Karloff, but I'm easily confused these days. <img src ="https://s-media-cache-ak0.pinimg.com/236x/07/c6/be/07c6be787ac48bc74111af0a612ade7a.jpg"> By the way, if the answer is 15, shouldn't the sum be 5 + (1 X 10)? I still think the answer is Boris Karloff.

Brackets not needed, it's clear with or without them. Multiplication comes before addition. Ask Mad Mark........

It's not void, brackets not needed, always do multiplication before addition. Agreed that brackets would be clearer though, but they're optional.

Twenty five years in Payroll and that's the first time I've heard that. Probably explains why I never paid t'owd man & tingleytyke correctly!

Isn't the rule that multiplication and division comes before addition and subtraction UNLESS there are brackets? 5+1x10=15 5+(1x10)=15 (5+1)x10=60

The answer is BIDMAS ie Brackets Indices Division Multiplication Addition Subtraction Order of operations

It's called BODMAS and means that things should be done in a certain order. Brackets first Orders second Division and Multiplication third Addition and Subtraction last

Have a go at some of these. They are a bit easier... http://mathworld.wolfram.com/UnsolvedProblems.html
