Tens digit of a number

A number consists of individual digits. Depending on which digit of the number you are looking at, it has a different one Names.

• A one-digit number only has a one-digit number. A two-digit number already has a units digit and a tens digit. A three-digit number has a ones digit, a tens digit, and a hundreds digit, and so on.
• As you can see, the different digits do not have their names arbitrarily, but there is a system behind them. You can easily remember the names. Just think about what happens if you change just one digit of a number and leave the rest of the number the same.
• For example, if you change the number 952 to 962, you have only changed the number in the second position, i.e. 5 to 6. You have increased the number by 10, so it is the tens digit.

An example on the subject

There are many simple tasks you can ask yourself on this subject.

• Suppose you have an unknown two-digit number. If you swap the two digits, the number increases by 18. What could the starting number be? If you try it, you will quickly come across the number 13, which turns into 31 after swapping its digits. Can you find any other numbers that meet the requirement?
• What is interesting is that even if all the other digits get smaller, it is enough to increase one digit to make the number larger. For example, 7437> 6879 applies. You just increased the thousands digit by one. Although all the other digits (the hundreds, tens, and units) have become smaller, the new number is still larger than the old number.

You can look at many other simple examples too Counting and make their digits. You don't even need a book for that. Just think of different tasks.
