To find -

The addition of $11+12+13+14+15+16+17+18+19+20$

Solution -

Add means mixing two values.

Given equation ,

$11+12+13+14+15+16+17+18+19+20$

Add 11 and 12 we get

= $23+13+14+15+16+17+18+19+20$

Add 23 and 13 we get

= $36+14+15+16+17+18+19+20$

Add 36 and 14 we get

= $50+15+16+17+18+19+20$

Add 50 and 15 we get

= $65+16+17+18+19+20$

Add 65 and 16 we get

= $81+17+18+19+20$

= $98+18+19+20$

Add 98 and 18 we get

= $116+19+20$

Add 116 and 19 we get

= $135+20$

Add 135 and 20 we get

= $155$

∴ The addition of $11+12+13+14+15+16+17+18+19+20$ is 155 .
