6*10 + 12*1 = 60 + 12 = 72
When adding up columns (not colums) of figures it is critical that figures with the same place value are added together (see below). Lining up the decimal points ensures that this is the case. If place vales were not lined up, 12 + 23 could be 242 (unit value of 23 lined up with tens value of 12), or 143 (tens value of 23 lined up with unit value of 12) or 35 (units and tens correctly aligned).
How about 12 to begin with
To determine the number of times the digit 1 appears between 1 and 120, we can consider each place value separately. In the units place, the digit 1 appears 12 times (1, 11, 21, ..., 111). In the tens place, the digit 1 appears 11 times (10, 11, 12, ..., 19). Therefore, the total number of times the digit 1 appears between 1 and 120 is 12 (from the units place) + 11 (from the tens place) = 23 times.

382 = 12 + 70 + 300
12 tens mean there are 1 tens and 2 ones, as only one digit can occupy a column.
It is 12000+120+1200+112 = 13432.
In 12000, there are;12 thousands120 hundreds and1200 tens
To find the number that is the same as 6 tens and 12 ones, we need to understand the concept of place value. In the number 6 tens and 12 ones, the digit 6 represents the number of tens and the digit 2 represents the number of ones. Therefore, the number is 62.
Seven hundreds = 7 x 100 = 700 Eleven tens = 11 x 10 = 110 Twelve ones = 12 x 1 = 12 So; 700 + 110 + 12 = 822 The answer is 822.
9 tens + 12 ones = 9 × 10 + 12 × 1 = 90 + 12 = 102.
129407 Is the right answer
