+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?
