Mathematical Symbols Puzzles
We all come across many mathematical or numerical puzzles, which are based on the usage of mathematical symbols or notations. At times such puzzles can even be solved by changing the way things are written.
In this post I am presenting 3 such interesting puzzles. Keen observation and simple application of logic is required to solve them. So here you go -
- Make this equation valid with single stroke of pen (i.e. just by adding a line somewhere): 5+5+5 = 550
- Make 120 using 5 zeros. You can use any mathematical notation/symbol
- What mathematical symbol can be put between 5 and 9, to get a number bigger than 5 and smaller
