Answers to Questions (FAQ)
What is a calculation with blank operators? (Definition)
A calculation with blanks without operator is a calculation with missing operation signs. This is a classic school exercise which consists in finding the possible operations to make the calculation true.
How to solve a calculation with blank operators?
The resolution of calculation with blank (missing operations) consists of finding the possible operations, for example, it is impossible to divide by 0. Also multiplications introduce large numbers, so they must be avoided if the result is small. Non-integer divisions are generally to be avoided.
Example: 1 ? 2 ? 3 = 0 has for solution 1 + 2 - 3 = 0
Example: (1 ? 2 ? 3) ? 4 = 0 has for solution (1 + 2 - 3) * 4 = 0
dCode also has a similar solver for numbers with missing digits.
How does the missing numbers solver work?
The program handles the 4 operators (addition +, subtraction -, multiplication * and division /), the equal sign =, but also the upper and lower operators > and <.
The blanks should be replaced with ? (Question marks).
If there is no comparison sign, then an equals sign will be used for an operator.
The solver uses a brute-force method, ie it tries all combinations and displays possible combinations.
The solver is limited to numbers and does not accept variables or letters in the calculation. Also, parentheses cannot be guessed and must be supplied.
What is the concatenation operator?
Concatenation is the action of linking elements.
Example: Concatenating the numbers 1 and 2 is creating the number 12.
