[Math4u] Re: 26 - 14 : 2 x 3 + 4² = ?

[Brian's comment to Princecharming134: This is useful information on how to make the "÷" sign. However the "/" sign has a very precise meaning and implies nothing. OK, you treated ":" as "( )/( )" but is this right or are you just making up stuff? Can you quote a reputable website?]

There is a division symbol available on your PC.

It looks like this ÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷

You can copy and paste it from this post if you wish or you may click
on "insert" then "symbols" then look for the division sign on
Microsoft word.

For those who are not aware as to how to make the division symbol,
they have been using ///////. the problem is that this can imply
either a fraction or a division sign.

My previous post I treated the : as a fraction.

26 minus 14 over 2 times 3 plus 4 squared.

In which case, you must complete all operations above and below the
fraction before you can divide.
