I will assume there were no parentheses in the problem, since
you didn't mention any. It will make a difference in the answer
if there are parentheses, because parentheses are to be done first.
6 times 6 plus 9 times 7 times 41 divided by 7 times 9
If you mean this:
6×6+9×7×41÷7×9
with no parentheses. There are no parentheses, so we look for exponents.
There are no exponents, so we look for multiplications and divisions left
to right. The first multiplication or division going left to right is
6×6 which gives 36. So we replace the 6×6 by 36, and copy everything else
over:
36+9×7×41÷7×9
There are no parentheses or exponents, so we again look for multiplications
and divisions left to right. The first multiplication or division going left
to right is 9×7 which gives 63. So we replace the 9×7 by 63, and copy
everything else over:
36+63×41÷7×9
There are no parentheses or exponents, so we again look for multiplications
and divisions left to right. The first multiplication or division going left
to right is 63×41 which gives 2583. So we replace the 63×41 by 2583, and copy
everything else over:
36+2583÷7×9
There are no parentheses or exponents, so we again look for multiplications
and divisions left to right. The first multiplication or division going left
to right is 2583÷7 which gives 369. So we replace the 2583÷7 by 369, and copy
everything else over:
36+369×9
There are no parentheses or exponents, so we again look for multiplications
and divisions left to right. The first multiplication or division going left
to right is 369×9 which gives 3321. So we replace the 369×9 by 3321, and copy
everything else over:
36+3321
There are no parentheses or exponents, nor any multiplications or divisions.
So we look for additions and subtractions left to right. There is only one
addition, so we end up with:
3357
If there were some parentheses, this answer will be wrong.
