Question

Сформулируйте правило сложения отрицательных чисел.Приведите примеры

Answer 1

При сложении отрицательных чисел получается отрицательное число, нужно к единицам первого числа, прибавить единица второго числа и перед этим результатом поставить "-".

Например: - 1 + (- 2) = - 1 - 2 = - (1 + 2) = - 3
- 57 - 43 = - (57 + 43) = - 100
- 1000 - 1 = - (1000 + 1) = - 1001

Answer 2

Rule for Adding Negative Numbers

When adding negative numbers, the key rule to remember is that adding a negative number is the same as subtracting the positive value of that number. This can be summarized as follows:

1. If you are adding a negative number, you can think of it as subtracting the positive value of that number.

Examples

- Example 1: Adding -5 and -3 - When adding -5 and -3, it can be thought of as subtracting the positive value of 5 from -3, which results in -8. - This can be expressed as: -5 + (-3) = -8.

- Example 2: Adding -7 and -2 - Adding -7 and -2 can be thought of as subtracting the positive value of 7 from -2, which results in -9. - This can be expressed as: -7 + (-2) = -9.

By following this rule, adding negative numbers becomes a matter of subtracting the positive values, which simplifies the process.
