Fill in the blank with $>, <$ or $=$ sign
$(- 21) - (- 10)$ ________ $(- 31) + (- 11)$

According to question,

L.H.S= $- 21 + 10$ ----------(multiplication of signs " $- \times - = +$ ")
= $- 11$

R.H.S= $- 31 - 11$ ----------(multiplication of signs " $+ \times - = -$ ")
= $- 42$

L.H.S is greater than R.H.S

So, sign $>$ is used to fill the blank

Fill in the blank with >, < or = sign(−21)−(−10)________(−31)+(−11)

According to question,L.H.S= −21+10----------(multiplication of signs "−×−=+") =−11R.H.S=−31−11----------(multiplication of signs "+×−=−") =−42 L.H.S is greater than R.H.S So, sign > is used to fill the blank

Fill in the blank with $>, <$ or $=$ sign
$(- 21) - (- 10)$ ________ $(- 31) + (- 11)$

According to question,

L.H.S= $- 21 + 10$ ----------(multiplication of signs " $- \times - = +$ ")
= $- 11$

R.H.S= $- 31 - 11$ ----------(multiplication of signs " $+ \times - = -$ ")
= $- 42$

L.H.S is greater than R.H.S

So, sign $>$ is used to fill the blank
