Question

Замените вычитание сложением и вычислите: (+6)-(-8); (-1)-(-3); (-9)-(+10); (+9)-(-5); (+4)-(+4); (-7,1)-(-7,1); (-7,1)-(+7,1); (+7,1)-(-7,1). ПОМОГИТЕ ПОЖАЛУЙСТА!!!!

Answer 1

(+ 6) - (- 8) = 6 + 8 = 6 + 8 = 14

(- 1) - (- 3) = (- 1) + 3 = 2

(- 9) - (+ 10) = (- 9) + (- 10) = - 19

(+ 9) - (- 5) = 9 + 5 = 14

(+ 4) - (+ 4) = 4 + (- 4) = 0

(- 7,1) - (- 7,1) = (- 7,1) + 7,1 = 0

(- 7,1) - (+ 7,1) = (- 7,1) + (- 7,1) = - 14,2

(+ 7,1) - (- 7,1) = 7,1 + 7,1 = 14,2

Answer 2

Substitution and Calculation of Expressions:

Let's substitute subtraction with addition and calculate the given expressions:

1. (+6)-(-8): - Substituting subtraction with addition: (+6) + (+8) - Calculating: (+6) + (+8) = +14

2. (-1)-(-3): - Substituting subtraction with addition: (-1) + (+3) - Calculating: (-1) + (+3) = +2

3. (-9)-(+10): - Substituting subtraction with addition: (-9) + (-10) - Calculating: (-9) + (-10) = -19

4. (+9)-(-5): - Substituting subtraction with addition: (+9) + (+5) - Calculating: (+9) + (+5) = +14

5. (+4)-(+4): - Substituting subtraction with addition: (+4) + (-4) - Calculating: (+4) + (-4) = 0

6. (-7,1)-(-7,1): - Substituting subtraction with addition: (-7.1) + (+7.1) - Calculating: (-7.1) + (+7.1) = 0

7. (-7,1)-(+7,1): - Substituting subtraction with addition: (-7.1) + (-7.1) - Calculating: (-7.1) + (-7.1) = -14.2

8. (+7,1)-(-7,1): - Substituting subtraction with addition: (+7.1) + (+7.1) - Calculating: (+7.1) + (+7.1) = 14.2

I hope this helps! If you have any other questions, feel free to ask.
