(x + 25 - x)^2 = 25^2 = 625
If i think the no. Is 6
Now 31-6= 25..
Sqr of 25 =625
My no = 3
Adding + 25
Total = 3+25 = 28
Sub (-3) = 28-3 = 25
Squaring = 25^2 = 625
This is not a complicated one and 25 remains always standard and so is the answer 625
A special integer exists in mathematics that shows a special property. If you subtract any number from that integer, the result will always be divisible by the successor of that number completely.
Do you know what that integer is ?
Guess a number 1-10, multiply it by 2, now add with 54 and divide by 2. Lastly, subtract the number you guessed 1-10. What number are you left with, and what is unusual about it?
Create the number 24 using (all of) 1,3,4 and 6. You may add, subtract, multiply and divide. Parentheses are free.
You must use each digit only once.
Note that you may not "glue" digits together. Powers are not allowed.
If x stands for 'add', y stands for 'subtract', z stands for 'divide' and p stands for 'multiply' then what is the value of (27 z 3) p 11 x 5?
