Try it.
\n" ); document.write( "I'll check your work.
\n" ); document.write( "============
\n" ); document.write( "I'll do a similar problem.
\n" ); document.write( "63 ÷ 3(4+3)
\n" ); document.write( "---
\n" ); document.write( "Add the numbers in the parentheses.
\n" ); document.write( "63 ÷ 3*7
\n" ); document.write( "Multiply
\n" ); document.write( "63 ÷ 21
\n" ); document.write( "= 3
\n" ); document.write( "------------------
\n" ); document.write( "Another opinion posted.
\n" ); document.write( "Figuring out which is right and which is wrong is educational.
\n" ); document.write( "---
\n" ); document.write( "Hint: it's a matter of order, or lack of parentheses.
\n" ); document.write( "==============
\n" ); document.write( "After some further thought:
\n" ); document.write( "8÷2(2+2) ---> (8/2)*(2+2) = 16
\n" ); document.write( "Or,
\n" ); document.write( "8/(2*(2+2)) = 8/8 = 1
\n" ); document.write( "I don't think the \"left to right\" resolves the ambiguity.
\n" ); document.write( "----
\n" ); document.write( "During 4 semesters of HS algebra, 2 semesters of college calculus, 1 semester of Diff Eqns and then \"Advanced Math for Engineers\" I never heard anything about \"left to right.\"
\n" ); document.write( "------------------------------
\n" ); document.write( "IDK when \"left to right\" became a rule.
\n" ); document.write( "And, the \"left to right\" violates PEMDAS by Dividing before Multiplying.
\n" ); document.write( "=====================
\n" ); document.write( "I think it was 4 semesters of college calculus. Been a while, not certain.\r
