you multiply first then you divide
Whatever you multiply or divide the numerator by, you must do the same to the denominator. If you multiply or divide the numerator and denominator by different numbers, you change the value of the fraction and turn it into a different number. After that, nothing is "equivalent" any more ... you're working with a changed number.
" ... multiply by the RECIPROCAL of the divisor.
multiply them and divide by two
You do not divide or multiply notations: you perform those operations on numbers which are expressed in different notations. How you do that depends on which notation you are concerned with.
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.

you divide and divide again then multiply then add then subtract then finally get the root
multiply
If you multiply integers the results is an integer. If you divide integers (with one exception) the result is a rational number which, in some cases, may be an integer. However, the exception is that division by 0 is not defined.

the answer becomes negative
1). First, ignore the signs. Just go ahead and multiply or divide the numbers as if they were both positive.Then, when you have that answer . . .2). If both of the original numbers had the same sign, then the answer is positive.If the original numbers had different signs, then the answer is negative.
