Not all the challenging questions are brain teasers, but all the brain teasers are obviously fun and challenging. Here we go, for one such brainstorming question! Mathematical puzzles mostly involve addition, subtraction, division, or multiplication. These four processes form the basis of any mathematical problem. Following the correct sequence of these operations gives us the exact solution to our question. The picture below will give you an idea of what this math puzzle is.
This question will let you think analytically and ponder your to search for all possible ways to get its solution. Though it looks complex, it is so easy when you find the exact way to solve it. The happiness and pride you feel after solving each of these mathematical expressions are incomparable. But if you were unable to solve this brain teaser check the next section to get the answer.
If 9999=4, 8888=8, 7654=18, What is 6543=? Brain Teaser for Sharp Minds- Solution
The most exciting part of all the puzzles is finding their solution. Here we are here to provide you with the best ways to get your solution. Normally, a mathematical expression involves one or more of the four processes mentioned above (i.e., addition, subtraction, division, and multiplication). But using simple calculations with the right sequence is all you need to solve these mathematical expressions.
If 9999=4, 8888=8, 7654=18, What is 6543=? Brain Teaser for Sharp Minds
9999=4
8888=8
7654=18
6543=?
The pattern followed here is
9999=4
(10-1)(10-1)(10-1)(10-1)
Now adding the number subtracted from 10 we get 1+1+1+1 = 4
8888=8
(10-2)(10-2)(10-2)(10-2)
Adding the number subtracted from 10 we get 2+2+2+2 = 8
7654=18
(10-3)(10-4)(10-5)(10-6)
3+4+5+6 = 18
Similarly
6543=
(10-4)(10-5)(10-6)(10-7)
4+5+6+7 = 22
6543=22
Mathematical puzzles may seem challenging at first but when you find the solution for your first puzzle, you will get yourself wanting more of them. You need not be a mathematical expert to solve these kinds of puzzles. All you need is at most concentration, creative thinking, and little mathematical knowledge.
