10 · Ten tens bundled together make exactly one hundred.
True · Ten groups of ten ones bundle together to make a hundred.
100 · 10 ten-blocks = 10 tens = 100.
10 tens · Ten ten-blocks together show a hundred. Ten ones only show a ten.
10 tens · 100 is exactly 10 tens. 10 ones is 10, 10 hundreds is 1000 and 100 tens is 1000.
