Question

Сравни числа в первой и во вторых строках. 1 строка 6.7.8.9. 2 строка 16.17.18.19. найди сумму чисел в первой строке.? как можно быстрее вычислить сумму чисел во второй строке?

Answer 1

Числа во второй строке последовательно на 10 больше, чем в первой.
6+9+(7+8)=30
16+19+(17+18)=35+35=70 так проще вычислить сумму

Answer 2

18+16+(19 +17)=70  2 строка        8+6+(9+7)=30 1 строка

Answer 3

Comparing Numbers in the First and Second Lines

To compare the numbers in the first and second lines, we have the following:

First line: 6, 7, 8, 9 Second line: 16, 17, 18, 19

Finding the Sum of Numbers in the First Line

To find the sum of the numbers in the first line (6, 7, 8, 9), we can simply add them together:

6 + 7 + 8 + 9 = 30

Therefore, the sum of the numbers in the first line is 30.

Calculating the Sum of Numbers in the Second Line

To calculate the sum of the numbers in the second line (16, 17, 18, 19), there are several ways to do it. Here are a few options:

1. Manual Addition: You can manually add the numbers together:

16 + 17 + 18 + 19 = 70

Therefore, the sum of the numbers in the second line is 70.

2. Using a Calculator: If you have a calculator or a calculator app, you can simply enter the numbers and use the addition function to get the sum.

3. Using a Programming Language: If you are familiar with programming, you can write a simple program to calculate the sum of the numbers. Here's an example in Python:

   numbers = [16, 17, 18, 19]
   sum_of_numbers = sum(numbers)
   print(sum_of_numbers)
   

When you run this program, it will output the sum of the numbers, which in this case is 70.

These are some of the ways you can quickly calculate the sum of the numbers in the second line. Choose the method that is most convenient for you.
