To get a positive result when multiplying two numbers, the numbers must have the same sign. So reciprocals must have the same sign. To find the reciprocal, keep the same sign and invert the fraction. The number zero does not have a reciprocal. Why? A number and its reciprocal multiply to [latex]1[/latex].

The answer contains no more significant numbers than the least accurately known digit for multiplying and dividing significant figures. If a number has more digits than the required number of significant digits, the number can be rounded. For instance, 434,500 is 435,000 to three significant digits.
Nov 09, 2010 · 62.Most people I’ve asked this question to simply respond “Because 2 minus-signs result in a plus-sign”, but are unable to explain why that is the case. A more detailed answer I received was that “multiplying a number with -1 is equal to the opposite of this number. So multiplying 2 negative numbers -a and -b can be written as (-1)a(-1)b.

Multiplying and Dividing *Integers Dividing (Continued) IDS S We already know how to divide two positive integers. For example, (+12) + (+4) = (+3), since division is the opposite of multiplication and (+3) x (+4) = (+12). In a similar way, (—12) + (+4) = (—3) since (+4) x (—3) = -12.
