Each student will collect 21 leaves (5+3+7+6). Therefore 18 x 21 = n or 18 x 21 = 378 leaves.
You can round the amount of leaves to about 20 and the amount of people to about 20 to get an estimate of about 400 leaves. 20 x 20 is a simple problem that doesn't need a calculator. 400 is very reasonably close to 378.
