485 · 400 + 80 + 5 = 485.
3 hundreds · The 3 is the hundreds digit, so it represents 3 hundreds.
3 hundreds · The 3 is the first digit, so it sits in the hundreds spot. It means 3 hundreds.
False · The 9 is the last digit, so it tells the ones. The first digit, 7, tells the hundreds.
60 · The 6 is the tens digit, so its value is 60.
That the 8 means 8 hundreds, not just eight · Reading digits like separate words hides their real value. The 8 in 802 stands for 8 hundreds.
400 + 80 + 5 · 400 + 80 + 5 = 485. The rest add to 413, 125 and 530.
True · Lena is right: 200 + 50 + 9 = 259.
She swapped the tens and ones digits · In 405, the middle digit is 0 tens and the last digit is 5 ones. Mia swapped them.
It has 0 tens · 706 has 7 hundreds, 0 tens and 6 ones, so only the 0 tens claim holds.
