7 tens and 20 ones is 7 × 10 + 20 × 1 = 70 + 20 = 90 (ninety).

Having: 9 ten-thousands → 90,000 the same number of thousands as ten thousands → 9 ten-thousands: 9 thousands → 9,000 8 fewer hundreds than ten-thousands → 9 ten-thousand: 9 - 8 = 1 hundreds → 100 6 more tens than hundreds → 1 hundreds: 1 + 6 = 7 tens → 70 6 fewer ones than thousands → 9 thousands: 9 - 6 = 3 ones → 3 → the number is 90,000 + 9,000 + 100 + 70 + 3 = 99,173.
6 + 7 = 13 13 can't fit into the ones place. Regroup 13 ones into one ten and three ones. Leave the three ones in the ones place and carry the one ten over to the tens place.
7 lots of 1000s 5 lots of 100s 6 lots of 10s and 1 lot of 1.

We expand 715 into 7 hundreds, 1 ten, and 5 ones. This can be written as 7(100) + 1(10) + 5(1) = 715.
7 ten thousands 9 hundredths 3 ones 6 hundreds 7 tens = 71,573
10-7 is the same as 1/107, or 0.000 000 1 So 3*10-7 = 0.000 000 3 In words, 10-7 is one in ten million. So you are talking about three in ten million.
