30 · 300 = 30 tens.
3 hundreds · The 3 is the hundreds digit, so it means 3 hundreds.
3 · 300 is made of 3 groups of a hundred, so it has 3 hundreds.
True · 700 is just 7 hundreds. There are no tens or ones to add.
500 · 300 + 200 = 500.
800 · 8 hundreds is 800. The 8 sits in the hundreds spot, and two zeros come after it.
400 · The steps add 100, so 300 + 100 = 400.
True · Lena is right: 30 tens = 300, with 0 ones left.
He mixed up hundreds and tens: 900 has 9 hundreds and 0 tens · 900 only has a digit in the hundreds spot. The tens and ones spots are both 0.
300 · The steps of 100 need 300 in the gap.
