No, it can't be. The product of an odd number of negatives is negative.The product of an even number of negatives is positive.(The product of each two of your 6 negatives is positive, so you wind upwith the product of three positive numbers.)
Because all of the digits are negative so your just going to get a negative number
-12 - (-3) Two negatives equal a positive. So, -12 + 3 = -9
Well, it would depend on what number the positives and negatives are.For example:1+1+2+(-4)= -1or4+7+3+(-2)= 12
When multiplying two numbers together when negatives are involved, first multiply them together normally. In this case, 2x3=6 The next step is to find out if it's +6 or -6. You need to luck at the question again: If we multiplied two positives, the answer is positive. If we multiplied two negatives, the answer is positive. Otherwise, the answer is negative. In the question, we multiplied a positive by a negative, so the result will be negative. The answer, therefore, is -6
