Question

Evaluate or slove each expression [11+(20÷10)]×7

Answer 1

PEMDAS, you can do a quick search on google for images only, there are some nice pictures of it you might like.

we do the grouping first, from innermost to outmost, and peMDAS, we do MD before any AS.

`\bf [11+(20/ 10)]* 7\implies \stackrel{\mathbb{PEMDAS}}{[11+(\stackrel{\downarrow }{2})]* 7}\implies [\stackrel{\downarrow }{13}]* 7\implies 91`
