Answer 1

36+63
33+66так что ли какой класс

Answer 2

3+6=9 6-3=3 3-6=-3 -6+3=-3 -6-3=-9 -3+6=3 -3-6=-9 И т.д.

Answer 3

Task Explanation

To solve this problem, we need to find the sum of all two-digit numbers where the digits are either 3 or 6. The numbers can have repeating digits, and we need to calculate the sum of all such numbers.

Solution

To find the sum of all two-digit numbers with digits 3 and 6, we can use the following approach:

1. Count the occurrences of 3 and 6 in the tens and ones places. 2. Use these counts to calculate the sum of all possible two-digit numbers with digits 3 and 6.

Let's proceed with the solution step by step.

Counting Occurrences of 3 and 6

We can count the occurrences of 3 and 6 in the tens and ones places using the following information from the search results:

- From Source we have the following information: - 9, 90, 900 - Various mathematical operations and equations involving numbers.

- From Source we have the following information: - 68 - Other numbers mentioned in a context that is not directly related to our task.

- From Source we have the following information: - A date-related context not directly related to our task.

- From Source we have the following information: - A mathematical expression involving subtraction and multiplication.

- From Source we have the following information: - A numbered list with some mathematical context.

- From Source we have the following information: - A sequence of numbers and a context not directly related to our task.

- From Source we have the following information: - A reference to Mathematica software and its capabilities.

- From Source we have the following information: - A reference to a year and some context not directly related to our task.

- From Source we have the following information: - A sequence of numbers and a question related to the sequence.

- From Source we have the following information: - A date-related context not directly related to our task.

Calculating the Sum

Using the counts of occurrences of 3 and 6 in the tens and ones places, we can calculate the sum of all possible two-digit numbers with digits 3 and 6.

Let's proceed with the calculation.

Sum Calculation

The sum of all two-digit numbers with digits 3 and 6 can be calculated as follows: - The numbers with 3 in the tens place and 6 in the ones place are: 36. - The numbers with 6 in the tens place and 3 in the ones place are: 63.

Therefore, the sum of all such numbers is: 36 + 63 = 99.

The sum of all two-digit numbers with digits 3 and 6 is 99.
