Before going to the main riddle, let us see how we can solve two simple problems of mathematics. Questioned 3.3 big or 3.03 stars? The answer is very simple. Certainly 3.3 stars. But what is the simple logic of mathematics? We will look for the solution, the first digit of the two numbers is 3. So this is equal to two. Then there are two numbers in the decimal point. Both of them are equal. The first digit after the decimal point is 3, but the second digit is 0. From here I can say that the first number is big. Or, in other ways, can judge this last part. After 3-in the first issue (.3) = (3/10) = (30/100). But in the second issue (.03) = (3/100). Now compare the first and second digits, the first digit is the largest.
Find out how to solve another simple problem. The question is, if 7 C = 7 ÷ 7 × 7 ÷ 7 × 7, then what is the value of A? To find out the answer, a basic formula of arithmetic should be kept in mind. That is, if there is a bracket in an equation, then the inner work of the brackets, then the work of the division and then the addition and subtraction is to be done. There are no brackets here. Therefore, according to the rules, 7 ÷ 7 × 7 ÷ 7 × 7 = (7 ÷ 7) × (7 ÷ 7) × 7 = 1 × 1 × 7 = 7 By condition, 7C = 7 So C = 1
This week's puzzle
Say if (1 + 3) = 4, (2 + 4) = 10, (3 + 5) = 18, then in this section (6 + 8) = how much?

The puzzle was such that if the sum of three periodical numbers 9 is the sum of three random numbers and the sum of three is equal to 35, then what is the number three?
Answer:
Number three is 1, 3 and 5
Everyone has sent the correct answer. Thank you all.
How did you answer?
First, remember that because the sum of the three numbers in the transitional section is 9, so three times the number between that section is surely 9 plus. Because, if the middle number is a, then its previous and next number will be two (a-b) and (a + b). Then the sum of the number three = (a-b) + (a) + (a + b) = 3a = 9
So C = 3. Now let's see how many numbers can be three. If 2 is 3 and 4, then the sum of the three squares is equal to (4 + 9 + 16) = 29 But we want 35. So this is not the right answer. If 1, 3 and 5, then that is our answer. Because, the sum of each of them is equal to = (1 + 9 +25) = 35
