Question

A snail climbs a wall 30 cm and falls back 11 cm in a day. How much will it climb in 4 days?

Answer 1

The answer for the question is 120 - 44 = 76 cm

Answer 2

I think if it climbs 30 cm and falls back 11 cm so it is climbing 19 cm

30-11=19

so in 4 days it would climb 19*4 that is 76 cm

or

30 * 4 - 11 * 4 =?

120 - 44= 76

30-11+30-11+30-11+30-11=76
