Question 111612
First look for multiple operation signs, symbols, and numbers.

Identify the operations represented by the signs (+, -, x, χ).

Decide which operations to do first; if you have a problem that has parentheses and/or exponents, then you follow the order of: 

{{{P}}} (parentheses), {{{E}}} (exponents), {{{M}}} (multiplication), {{{D}}} (division), {{{A}}} (addition), {{{S}}} (subtraction)


2+3[10(4*5-16)-30]………first do operations in ( ….); multiply {{{4}}} and {{{5}}}, then subtract {{{16}}}

2+3[10(4)-30]………. Then do operations in [ ….]; multiply {{{10}}} and {{{4}}}, then subtract {{{30}}}

2+3[10]……….multiply {{{3}}} by {{{10}}}

{{{2+30}}}……….add

{{{32}}}
