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
Twenty-five rounding to ten's place are: What is 12 rounded to the nearest tens? What is 17 rounded to the nearest tens? What is 231 rounded to the nearest tens? Is 268 rounded to the nearest tens 260? Is 1074 rounded to the nearest tens 1100? Why is 648 rounded to the nearest tens not 640? How do you know that 7386 rounded to the nearest tens is not 7380? What is 36988374647 rounded to the nearest tens? How do you decide what 89473 should be rounded to? Round the following numbers to the nearest tens place" 13 783987 173676 98731 392 69837 76734 25555 876355 76754 777 54 769 47659 38

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
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

620=500+12 tens 12 tens=12*ten=120 500+120=620 couldn't had just googled it?
