Question

Пользуясь правилом знаков , запишите без скобок и вычислите: 1)(-14,35)-(-53,5)-(+21,3)-(-16 целых 3/20) 2)(-60)-(-15,9)-(+8,2)-(-23,3) 3)24,6+(-35,9)-(-6,5)+(-5,2) 4)(-32)-(-13,8)-(+26,3)-(-27,5) помогите пожалуйста

Answer 1

(-14,35) - (-53.5) - (+21,3) - (16 3/20) = 34
(-60) - (15,9) - (+8,2) - (-23,3) = -29 
24,6 + (-35,9) - (-6,5) + (-5,2) = -10 
(-32) - (-13,8) - - (+26,3) = (-27,5) = -17

#### Calculation using the Order of Operations To solve the given expressions using the order of operations, we need to follow the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Let's calculate each expression step by step: 1) (-14.35) - (-53.5) - (+21.3) - (-16 + 3/20): - First, let's simplify the expression inside the parentheses: -16 + 3/20 = -319/20. - Now, we can rewrite the expression: (-14.35) - (-53.5) - (+21.3) - (-319/20). - Next, let's simplify the subtraction of negative numbers: (-14.35) + 53.5 - 21.3 - (-319/20). - Finally, let's calculate the expression: -14.35 + 53.5 - 21.3 - (-319/20) = -14.35 + 53.5 - 21.3 + 15.95 = 33.8. 2) (-60) - (-15.9) - (+8.2) - (-23.3): - Let's simplify the subtraction of negative numbers: (-60) + 15.9 - 8.2 - (-23.3). - Now, we can calculate the expression: -60 + 15.9 - 8.2 + 23.3 = -29. 3) 24.6 + (-35.9) - (-6.5) + (-5.2): - Let's simplify the subtraction of negative numbers: 24.6 + 35.9 - 6.5 + 5.2. - Now, we can calculate the expression: 24.6 + 35.9 - 6.5 + 5.2 = 59.2. 4) (-32) - (-13.8) - (+26.3) - (-27.5): - Let's simplify the subtraction of negative numbers: (-32) + 13.8 - 26.3 - (-27.5). - Now, we can calculate the expression: -32 + 13.8 - 26.3 + 27.5 = -17. Therefore, the results of the given expressions are: 1) (-14.35) - (-53.5) - (+21.3) - (-16 + 3/20) = 33.8 2) (-60) - (-15.9) - (+8.2) - (-23.3) = -29 3) 24.6 + (-35.9) - (-6.5) + (-5.2) = 59.2 4) (-32) - (-13.8) - (+26.3) - (-27.5) = -17 I hope this helps! Let me know if you have any further questions.

#### Calculation using the rules of signs: 1) (-14.35) - (-53.5) - (+21.3) - (-16 + 3/20) 2) (-60) - (-15.9) - (+8.2) - (-23.3) 3) 24.6 + (-35.9) - (-6.5) + (-5.2) 4) (-32) - (-13.8) - (+26.3) - (-27.5) Let's calculate each expression step by step: 1) (-14.35) - (-53.5) - (+21.3) - (-16 + 3/20) = -14.35 + 53.5 - 21.3 - (-16 + 3/20) = -14.35 + 53.5 - 21.3 - (-16 + 0.15) = -14.35 + 53.5 - 21.3 - (-15.85) = -14.35 + 53.5 - 21.3 + 15.85 = 23.15 2) (-60) - (-15.9) - (+8.2) - (-23.3) = -60 + 15.9 - 8.2 - (-23.3) = -60 + 15.9 - 8.2 + 23.3 = -29 3) 24.6 + (-35.9) - (-6.5) + (-5.2) = 24.6 - 35.9 - (-6.5) + (-5.2) = 24.6 - 35.9 + 6.5 + (-5.2) = -9 4) (-32) - (-13.8) - (+26.3) - (-27.5) = -32 + 13.8 - 26.3 - (-27.5) = -32 + 13.8 - 26.3 + 27.5 = -17 Therefore, the calculations are as follows: 1) (-14.35) - (-53.5) - (+21.3) - (-16 + 3/20) = 23.15 2) (-60) - (-15.9) - (+8.2) - (-23.3) = -29 3) 24.6 + (-35.9) - (-6.5) + (-5.2) = -9 4) (-32) - (-13.8) - (+26.3) - (-27.5) = -17 I hope this helps!
