Question

Choose any 3 digit number describe how to find the number that is 10 more

Answer 1

Let's divide this question into two parts:
1. Choosing any 3 digit number.
2. Find the number that is 10 more.

1. Let choose the number 111. As you can see it is the three digit number.
2. Now to find the 10 more to 111, we have to add 10 to 111 as follows:

111
+10
--------
121

Hence, the 10 more to the number 111 is 121.

Answer 2

So suppose you have the number 346.  The basic equation for this would be 346 + 10, but I will show you a shortcut to solve it. These are the steps:

1. Break the number down into digits:           3    4    6
2. Add 1 to the second digit (4):                         +1
                                                                      3    5    6
3. Your answer is 356!
