Answer 2

Перевожу ваш вопрос на английский язык: "Provide a detailed answer. Please help! Represent the number as the sum of two addends: a) 4 = 5 + (-1) = 9 + (-?) = -2 + ? = -3 + ? = -4 + ?; b) 8 = 9 + (-?) = 10 + ? = -3 + ? = -4 + ? = -5 + ?; c) -2 = -5 + ? = 5 + ? = -4 + ? = 4 + ? = -3 + ?; d) -5 = 4 + (-?) = -4 + ? = 3 + ? = -3 + ? = 0 + ?."

Representation of Numbers as the Sum of Two Addends

To represent a number as the sum of two addends, we need to find two numbers whose sum equals the given number. Let's go through each case you provided:

a) 4 = 5 + (-1): In this case, the sum of 5 and -1 equals 4. So, we can represent 4 as the sum of 5 and -1.

4 = 5 + (-1)

Next, we are given the following equations: 9 + (-?) = 4 -2 + ? = 4 -3 + ? = 4 -4 + ? = 4

To find the missing values denoted by "?", we need to solve these equations.

Solving 9 + (-?) = 4: Subtracting 9 from both sides, we get: -? = 4 - 9 -? = -5

Therefore, the missing value is -5.

Similarly, solving -2 + ? = 4: Adding 2 to both sides, we get: ? = 4 - 2 ? = 2

Solving -3 + ? = 4: Adding 3 to both sides, we get: ? = 4 - 3 ? = 1

Solving -4 + ? = 4: Adding 4 to both sides, we get: ? = 4 - 4 ? = 0

So, the missing values are -5, 2, 1, and 0.

b) 8 = 9 + (-?): In this case, the sum of 9 and -? equals 8. So, we can represent 8 as the sum of 9 and -?.

8 = 9 + (-?)

Next, we have the following equations: 10 + ? = 8 -3 + ? = 8 -4 + ? = 8 -5 + ? = 8

Solving these equations, we find the missing values:

Solving 10 + ? = 8: Subtracting 10 from both sides, we get: ? = 8 - 10 ? = -2

Solving -3 + ? = 8: Adding 3 to both sides, we get: ? = 8 - 3 ? = 5

Solving -4 + ? = 8: Adding 4 to both sides, we get: ? = 8 - 4 ? = 4

Solving -5 + ? = 8: Adding 5 to both sides, we get: ? = 8 - 5 ? = 3

Therefore, the missing values are -2, 5, 4, and 3.

c) -2 = -5 + ?: In this case, the sum of -5 and ? equals -2. So, we can represent -2 as the sum of -5 and ?.

-2 = -5 + ?

Next, we have the following equations: 5 + ? = -2 -4 + ? = -2 4 + ? = -2 -3 + ? = -2

Solving these equations, we find the missing values:

Solving 5 + ? = -2: Subtracting 5 from both sides, we get: ? = -2 - 5 ? = -7

Solving -4 + ? = -2: Adding 4 to both sides, we get: ? = -2 + 4 ? = 2

Solving 4 + ? = -2: Subtracting 4 from both sides, we get: ? = -2 - 4 ? = -6

Solving -3 + ? = -2: Adding 3 to both sides, we get: ? = -2 + 3 ? = 1

Therefore, the missing values are -7, 2, -6, and 1.

d) -5 = 4 + (-?): In this case, the sum of 4 and -? equals -5. So, we can represent -5 as the sum of 4 and -?.

-5 = 4 + (-?)

Next, we have the following equations: -4 + ? = -5 3 + ? = -5 -3 + ? = -5 0 + ? = -5

Solving these equations, we find the missing values:

Solving -4 + ? = -5: Adding 4 to both sides, we get: ? = -5 + 4 ? = -1

Solving 3 + ? = -5: Subtracting 3 from both sides, we get: ? = -5 - 3 ? = -8

Solving -3 + ? = -5: Adding 3 to both sides, we get: ? = -5 + 3 ? = -2

Solving 0 + ? = -5: Subtracting 0 from both sides, we get: ? = -5 - 0 ? = -5

Therefore, the missing values are -1, -8, -2, and -5.
