But while we're at it, what's 10*2+15/5+6*4-10=?
It's sad that when I see those questions on FB, most people get them wrong.
Well, since the answer will depend on which operator precedence rule is used, not too surprising that most get it wrong. The "right answer" usually assumes one precedence order, I have run into half a dozen different ones over the years and have not kept up with which one is currently in favor and with which group of mathematicians. There is a reason parentheses are supposed to be used when presenting such an equation.
