Step 1: Let's Learn

Read it, or press Listen and follow the words.

The rule has not changed. Compare the tens first.

Bigger numbers, same steps

73 and 68. 7 tens beats 6 tens, so 73 is greater.

If the tens tie, compare the ones. 45 is less than 47.

Start from the biggest place

Compare hundreds, then tens, then ones. Stop at the first difference — the rest cannot change the outcome.

More digits usually means bigger

A three-digit number beats a two-digit one, because it has hundreds the other has none of.

Step 2: Try It Yourself

Tap and try it out.

Count the rods first. Then choose the symbol.
Left
73
Right
68

73 is greater than 68.
