It seems like there should be an operation between "six" and "five"

"9 divided by 3" and "2 divided by 4" can be evaluated simultaneously.

subtract 7 from 21

Expressions within parenthases (brackets) should be done first. Then each operation should be done in turn from left to right. Therefore 4+7x(5+4) would be 4+7x9 and then 11x9 =99.

You don't have the complete question here. "...between a number" and what? First figure out what operation is being used, and then put that operation in the place of the "and" in the statement. Since difference is subtraction, you will put a minus sign in place of the "and" that should be after the word, "number." So, your answer will be as follows: 4/(x - ___) Fill in the blank with what ever is says after the word, "number,"

0.6

That means that wherever you spot a numerator and denominator that have a common factor,you should should divide the numerator and denominator by their common factor.This operation doesn't change the value of an expression, but it 'simplifies' it. The operation isalso the heart and soul of measurement-unit conversions.It means that if you spot a numerator and denominator that have a common factor, then you should divide the numerator and denominator by their common factor.This operation doesn't change the value of an expression, but it 'simplifies' it. The operation is also the heart and soul of measurement-unit conversions.It means, if you can cancel, cancel. Otherwise don't.This usually refers to simplifying fractions that involve numbers or variables. If the same variable, or factor, appears in the top and in the bottom, you can eliminate it from both without changing the result.

There is no known origin of the order of operations or PEMDAS. PEMDAS is considered as the proper way to tackle a given mathematical expression in terms of what operation should be performed first.
