Math Puzzles

Just like math tricks, math puzzles are also answered sometimes out of boredom. These days, Sudoku has been acquiring popularity amongst high school and elementary students. It is like a magic square. Sudoku is an enjoyable math puzzle game that only requires concentration and logic.

There is only one rule to solve Sudoku. You have to fill in the board so that the numbers 1-9 appear exactly once in a column, row and in a three by three box. The Sudoku is initially filled in with numbers. You should fill the empty boxes. Apply the rule above while solving the math puzzles. However, the diagonals are not considered.

 

Remember that the initial numbers inside are to be left unchanged. Focus on the goal to fill the whole puzzle by numbers from 1-9.

 

 

Sudoku can be modified. Some Sudoku math puzzles feature unique modifications from basic and simple Sudoku. Try to modify one Sudoku. Experiment with different games and explore to see exciting variations. After discussing Sudoku puzzles, try to answer this critical-thinking puzzle:

“What is the sum of all the integers from 1 to 100.” Since this is a puzzle, there’s an easier way to solve it. Hint: Remember the pairing strategy for adding numbers.

The math puzzle can be answered with this solution:

Since the given can be expressed as (1+2+3+…..98+99+100). Take a look at (1+100, 2+99, 3+98…). It has a pattern and with a common sum of 101. All pairs have the sum of 101. By multiplying 101 to the number of pairs, we can actually get the sum of the whole series. Since there are 50 pairs, the equation would be 50 x 101= 5050.
