The answer is 0.

2

2 + 2 - 4 = 0

4 - 7 + 14 + 2 - 19 + 6 = 0

Zero minus (or plus) any number is that number. To clarify: 0 - (-2) = 2 0 - (-36) = 36

1 + 1 - 2 = 0

A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9

Answer: 0

4

2 + 2 + 2 + 2 + 2 + 2 + 2 -14 = 0

The sum is 96.

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

1/2 = 25/50

6 - 1 * 0 + 2 / 2 = 7

=1

In Winter - Cold, about minus 0 to minus 40 Celsius In Spring - Wet, about minus 0 to plus 15 Celsius In Summer - Hot, plus 20 to plus 40 Celsius In Autumn - Wet, plus 15 to minus 0 Celsius

18 + 12 + 0 - 4 - 10 = 16

It is: (3-3) times (6+2) = 0

yes you can. You can add and subtract ANY number, negative or positive, even if it is a decimal. For example 1 + 1 = 2 -1+-1 = -2 -1+1 = 0 A minus plus a minus is a minus. A minus plus a positive is a minus.

4

x2+2x-4 = 0 x = (-2 plus/minus sqrt (4-(4x1x-4)) / 2 x = (-2 plus/minus sqrt 20)/2 x = (-2 - sqrt 20)/2 or (-2 + sqrt 20)/2 x = -3.236 or 1.236

It is 5.

2 minus 2/5 plus 1/2 minus 4 = -1.9
