Negative plus a negative is a negative. Ex. -1+-1=-2 Negative times a negative is a positive. -2*-2=4 But a negative [minus] plus a positive [plus] can be minus, zero or plus: For example, -3 + 2 = -1 -3 + 3 = 0 -3 + 4 = +1
negative read this : "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
A negative minus a positive is a negative. i.e -1-(+1)= -2
-3 - (-1)= -3 + 1= -2-2
2 x -2 - 3 x 3 + -1 = (2 x -2) - (3 x 3) + (-1) = -4 - 9 - 1 = -14.
The answer is nine.
-1/5 minus -2/7 is 3/35
three
A plus times a plus is still a plus. Below is the way I remembered it: If there is not a minus sign, it is plus (positive). If there is 1 minus sign, it is minus (negative). If there are 2 minus signs, it is plus (positive).
negative 9 divided by negative 3 is 3 andnegative 3 minus 1 is negative 2
1 - -1 = 2
-1 - -1 = 0
