This is how to make commands for finding the minimum and maximum number from a string of one-digit numbers.

## Find Maximum Number Command

This command has to be called like this: 123. Typing 123 finds the maximum number out of 1, 2, and 3. It's possible to add as many numbers in the string.

### Creating the Command

The first step for creating the command is to make a block called Find Biggest Number and then add a number input called Number string. Make this code under the define block:

```define Find Biggest Number (Number string)
set [count v] to 
set [biggest number v] to 
repeat (length of (Number string))
change [count v] by (1)
if <(letter (count) of (Number string)) > (biggest number)> then
set [biggest number v] to (letter (count) of (Number string))
end
end```

### Using the Command

Now make a script like this one to test the command:

```Find Biggest Number (123) :: custom
say (biggest number)```

If the program is correct, the sprite should say the number 3. If the sprite says no number or another number, check the define block's script.

## Find Minimum Number Command

This command uses a similar approach to the find maximum number command. The command is called the same way as the maximum number command.

### Creating the Command

The first step for creating this command is to make a block called Find Lowest Number and then add a number input called Number string. Make this code under the define block:

```define Find Lowest Number (Number string)
set [count v] to 
set [lowest number v] to  // start at 10 because otherwise the lowest number will always be 0
repeat (length of (Number string))
change [count v] by (1)
if <(letter (count) of (Number string)) < (lowest number)> then
set [lowest number v] to (letter (count) of (Number string))
end
end```

### Using the Command

Now make a script like this one to test the command:

```Find Lowest Number (123) :: custom
say (lowest number)```

If the program is correct, the sprite should say the number 1. If the sprite says no number or another number, check the define block's script.

## Uses For These Commands

They are used for some reasons, like:

1. Finding the maximum or minimum number of a number string.
2. Quizzes where someone guess the highest or lowest number.
