Fill in the boxes with numbers from 1-10. One number can be used only once.
4 9 10
1 6 5
Fill below squares with all the integers from 1 to 18 (using each number only once), such that each equation holds true?
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 ?
 +  +  = 30
Fill the boxes using one of these numbers 1, 3, 5, 7, 9, 11, 13, 15
You can also repeat the numbers.
Calculate the numbers in the order shown, do not change the order of the numbers.
Replace each question mark with a mathematical sign. Plus, minus, multiply and divide can each be used once only.
In which order should they be used to score 25?
6 ? 5 ? 7 ? 2 ? 3 = 25
