104. If there are an even number of minus signs in a multiplication, ignore them!
Robert Recorde, who designed the equals sign, introduced plus and minus in 1557. Brahmagupta was an Indian mathematician who invented the multiplication sign around the 19th century. Johann Rahn first used the division sign in his book Teutshe algebra in 1659.
In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example: +10 minus -20 = -10 If the plus sign is smaller than the minus sign, the answer will be a minus. For example: -10 minus + 20 = -10 In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example: +5 x + 2 = +10 -5 x - 2 = +10 -5 x +2 = -10
Work the problem the same as usual, but then prefix the answer with the appropriate sign. First perform the division--numerator divided by the denominator--without regard to the sign. The sign of your answer depends on the combination of the signs of the numerator, the denominator, and the fraction itself. * If there are an even number of minus signs, the answer is positive. * If there are an odd number of minus signs, the answer is negative. * If there are an no minus signs, the answer is positive.
Because both minus signs to be cut therefore minus * minus will be treated as plus numbers

There are many signs used in Excel. Three of them are the plus sign (+), the minus sign (-) and the multiplication sign (*).
multiplication signs: x , * , . , (Dot)
They are called operators because they operate all of the operators. Hope I helped!

Expressions can be all the operations including multiplication, exponents, roots, etc. but including the "verb" of the sentence, the relationship sign like equals.
64 This is just like regular multiplication but you have to pay attention to the signs. Here's a table that will help you determine what the sign of the answer should be: + x + = + + x - = - - x + = - - x - = +

If you're talking about multiplication or division, then opposite signs will result in a negative number.
