Question

i'm vry weak in maths can anybody help

Answer 1

I agreed yur too weak in MATHS but what yu will do with asking an answer of yur one question only???

Answer 2

All answers are correct but I think you need some explaining and some understanding.

Draw a line 10 inches long.

Centre of the line is at 5 inches. Put a small vertical line, call this Zero. Where vertical line meets 10 inches long line put a point.

Mark about same size small vertical lines at 1 inches on both sides of the zero.

Star on the right side of the zero

Now number them 1, 2, 3 ,4,

Start on left side of the zero and number then -1, -2, -3 -4.

Make sure that -1 and +1 are closest to the zero.

What you just did is drew a picture of sign convention.

Remember you have not written -5 or +5

Now draw a vertical line 1inch long on top of -5 location. Put a point at the end of at his line.

Go on the other side and draw a vertical line 2 inches long on top of +5 location. Put a point at the end of this line.

Join the two points by drawing a line.

Extend the small line to the top line, you will have nine vertical line.

From left to right each line is bigger(longer) then one to its left.

Vertical line at -2 is smaller the vertical line at -1.

I Hoping this visual aid will help you understand sign convention.

PS:

... ,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,+1,+2,+3,+4,+5,+6,+7,+8,+9,+...,

Other way to memember is that number to the right is greater.

Since number -1 is to the right of -2, -1 >-2

Answer 3

-1>-2

Answer 4

-1 > -2

Answer 5

-1 > -2

Answer 6

-1 is greater is because if you -1 with 3, you will get 2, but if you add -2 with 3 it is -1. Likewise,-1 is the greatest number than any other negative whole number.

Answer 8
