There are four solutions.
first number should be lie between 111 and 333
third number should be multiple of 3, so there unit digit sure.
Use digits from 1 to 9 once in such a way that each digit is used in the boxes and are not repeated.
With the help of the mathematical signs, the digits are supposed from the top to bottom and form a mathematical equation where each digit is used only once.
Use the digits from 1 up to 9 and make 100.
Follow the rules.
=> Each digit should be used only once.
=> You can only use addition.
=> For making a number, two single digits can be combined (example, 4 and 2 can be combined to form 42 or 24)
=> A fraction can also be made by combining the two single digits (example, 4 and 2 can be combined to form 4/2 or 2/4)
How can we do this ?
