7 x 10 = 70 ones

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

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.

For example, a seven in the tens place would equal to 70 whereas a 7 in the ones place equals 7.

17 tens = (10 + 7) tens = 10 tens + 7 tens = 1 hundred + 7 tens.

7 hundreds, 16 tens 4 ones is 7 x 100 + 16 x 10 + 4 x 1 = 700 + 160 + 4 = 864.

851 dollars. 7 hundreds (7*100) =700 14 tens (14*10) = 140 11 ones (11*1) = 11 700+140+11= 851

7 tens and 4 ones 5 thousandths = 74.005

3 tens is equal to the number 30, and 3 ones is equal to the number 3.So, 3 tens and 3 ones is 33; and 67 minus 33 (or 67 less33) is 34.You could also look at the number 67 and see that it is 6 tens and 7 ones. Then it is easier to say "6 tens and 7 ones minus 3 tens and 3 ones = 34"because:6 tens minus 3 tens = 3 tens, and 7 ones minus 3 ones = four ones.3 tens and four ones = 34
