Answer 1

Ответ:

Пошаговое объяснение:

1)-56+23+(-23) = -56 + (23 - 23) = -56+0 = -56

2)-75+30+(-15) = (-75-15)+30 = -90+30= -60

3)52+(-22+71) = (52-22)+71 =30+71=101

4)81+(-31+50) = (81 - 31)+50=50+50=100

5)46+(-20)+24 = (46+24)-20=70-20=50

6)69+(-29)+10 = (69 - 29) + 10 = 40+10=50

Calculations Using Different Methods

1) Using the Order of Operations (BODMAS/BIDMAS) - For the expression -56 + 23 - (-23): - First, solve the part within the parentheses: -(-23) = 23 - Then, perform the addition and subtraction: -56 + 23 + 23 = 0

- Result: 0

2) Using the Order of Operations (BODMAS/BIDMAS) - For the expression -75 + 30 - (-15): - First, solve the part within the parentheses: -(-15) = 15 - Then, perform the addition and subtraction: -75 + 30 + 15 = -30

- Result: -30

3) Using the Order of Operations (BODMAS/BIDMAS) - For the expression 52 - (-22) + 71: - First, solve the part within the parentheses: -(-22) = 22 - Then, perform the addition and subtraction: 52 + 22 + 71 = 145

- Result: 145

4) Using the Order of Operations (BODMAS/BIDMAS) - For the expression 81 - (-31) + 50: - First, solve the part within the parentheses: -(-31) = 31 - Then, perform the addition and subtraction: 81 + 31 + 50 = 162

- Result: 162

5) Using the Order of Operations (BODMAS/BIDMAS) - For the expression 46 - (-20) + 24: - First, solve the part within the parentheses: -(-20) = 20 - Then, perform the addition and subtraction: 46 + 20 + 24 = 90

- Result: 90

6) Using the Order of Operations (BODMAS/BIDMAS) - For the expression 69 - (-29) + 10: - First, solve the part within the parentheses: -(-29) = 29 - Then, perform the addition and subtraction: 69 + 29 + 10 = 108

- Result: 108
