A negative number divided by a positive number will be a negative number. For example: -20 / 4 = -5 -100 / 2 = -50 Here are the other cases of division by positive or negative numbers. A negative number divided by a negative number would be a positive number. A positive number divided by a positive number would be a positive number. A positive number divided by a negative number would be a negative number.
13 10 17 15 21 13 - 10 = -3 10 - 17 = +7 17 - 15 = -2 15 - 21 = +6 The negative numbers alternate with the positive numbers The negative numbers are augmented by +1 each step The positive numbers are diminished by -1 each sterp So the next step from 21 is a negative and should be -2 increased by +1 to -1 giving a new value of 20 Then the next step is a positive and should be +6 decreased by -1 to +5 giving 25 13 - 10 = -3 10 - 17 = +7 17 - 15 = -2 15 - 21 = +6 21 - 20 = -1 20 - 25 = +5
-x + 7 = 27 Subtract 7 from both sides: -x = 20 or x = -20
you need to reorder the problem by manipulating the numbers -2x-7=-x+13 group your variables and constants thus -x-2x=7+13 simplify -3x=20 simplify again x=-20/3
negative 20
Negative 15 plus positive 20 equals 20 minus 15, which equals 5.
The answer can be negative, zero, or positive. For example: -15 + 20 + (-10) = -5 -15 + 20 + (-5) = 0 -15 + 20 + (-2) = 3
17
-1+20 = 19
70
Equals positive or negative. Because minus a positiveequals plus a negative.(+15) - (+20) = (+15) + (-20)If you want to lear the rules, use a plus symbol between the parts of the operation.(+) + (+) = +(-) + (-) = -(+) + (-) = - or +Generally speaking, if just one number have a negative sign, the result can be both positive or negative.
20
If you add a positive number, another positive number, and a negative number, you can get anything - the result may be positive, negative, or zero. It all depends on the magnitudes of the numbers involved. For example: 10 + 10 - 1 = 19 (positive) 5 + 5 - 10 = 0 (zero) 5 + 6 - 20 = -9 (negative)
It is: -4/5 +3/20 = -13/20
-28

To multiply a negative and positive just multiply regularly and then make negative ex. 6*-5=-30 In general, here are the rules for multiplying signed numbers: positive x positive = a positive 4 x 5 = +20 positive x negative = a negative 4 x -5 = -20 negative x positive = a negative -5 x 4 = -20 negative x negative = a positive -5 x -4 = +20
