Question

Use the sign of `lt, gt` or `=` in the box to make the statement true(a) `(-8)+(-4)` __ `(-8)-(-4)` (b) `(-3)+7-(19)` ___ `15-8+(-9)` (c) `23-41+11` ___ `23-41-11` (d ) `39+(-24)-(15)`____ `36+(-52)-(-36)` (e) `-231+79+51` ___ `-399+159+81`

Answer 1

(a) `(-8)+(-4) = -12`
`(-8)-(-4) = -4`
So, `(-8)+(-4) lt (-8)-(-4)`

(b)`(-3)+7-(19) = -15`
`15-8+(-9) = -2`
So, `(-3)+7-(19) lt 15-8+(-9) `

(c)`23-41+11 = -7`
`23-41-11 = -29`
So, `23-41+11 gt 23-41-11`

(d)`39+(-24)-15 = 0`
`36+(-52)-(-36) = 20`
So, `39+(-24)-15 lt 36+(-52)-(-36)`

(e)`-231+79+51 = -101`
`-399+159+81 = -159`
So,`-231+79+51 > -399+159+81`
