Yantar

45

1) Subtracting 47 from 47 yields 0. When you subtract a number from itself, the result is always zero.

\[47 - 47 = 0\]

2) To find the sum of 82 and -18, you need to add the two numbers together. Positive numbers represent quantities greater than zero, while negative numbers represent quantities less than zero. Adding positive numbers yields a positive result, and adding negative numbers yields a negative result.

\[82 + (-18) = 64\]

3) The value of positive 43 added to negative 43 is zero. When you add a positive number and its corresponding negative, the result is always zero.

\[43 + (-43) = 0\]

4) To find the sum of negative 39 and negative 45, you simply add the two numbers together. When you add two negative numbers, the result is negative.

\[-39 + (-45) = -84\]

5) The sum of 36 and negative 36 is zero. When you add a number to its negative counterpart, the result is always zero.

\[36 + (-36) = 0\]

6) Adding 0 and negative 35 gives you -35. When you add zero to any number, the result remains unchanged.

\[0 + (-35) = -35\]

7) The sum of 94 and 6 is 100.

\[94 + 6 = 100\]

8) Adding negative 19 and negative 19 gives you the sum of negative 38. When you add two negative numbers, the result is negative.

\[-19 + (-19) = -38\]

9) The value of positive 1 added to 0 is 1. When you add zero to any number, the result remains unchanged.

\[1 + 0 = 1\]

10) To find the sum of negative 9 and positive 89, you add the two numbers together. When you add a negative number and a positive number, the result can be either negative or positive, depending on the magnitudes of the numbers. In this case, the sum is positive.

\[-9 + 89 = 80\]

11) Adding 21 and negative 41 gives you -20.

\[21 + (-41) = -20\]

12) The sum of negative 95 and positive 21 is -74.

\[-95 + 21 = -74\]
