+1 - 2 - 3 + 4 = 0 +5 - 6 - 7 + 8 = 0 +9 - 10 - 11 + 12 = 0 ........... +61 - 62 - 63 + 64 = 0.
If possible fill + or - for o and make this true, if not possible then provide the reasoning...
1 o 1/2 o 1/3 o 1/4 o 1/5 o 1/6 o 1/7 o 1/8 o 1/9 o 1/10 o 1/11 o 1/12 = 0
Use the numbers 2, 3, 4 and 5 and the symbols + and = to make a true equation. Conditions: Each must be used exactly once and no other numbers or symbols can be used.
Fill below squares with all the integers from 1 to 18 (using each number only once), such that each equation holds true?
ONE + ONE = TWO
Using neither of the numbers 1 or 2, replace each letter of the equation to make it true. Also, no letter is equal to zero.
If so, what is WETTEN?
Can you replace each alphabet with the number (1 - 9) to make below equation correct ?
AB * C = DE - F = GH / I
