Question

Сравнить примееры в каждом столбце.Чем онипохожи ичем отличаются? Выскажи предложение означениях этих выражений,равны ли они? 72-(24+26)= (72-24)-26= (48+49)-39= 48+(49-39)= проверитьсве предложение, выполнить вычисления

Answer 1

72-(24+26)=(72-24)-26
72-50=48-26
22=22

(48+49)-39=48+(49-39)
97-39=48+10
58=58

Answer 2

Comparing Examples in Each Column

To compare the examples in each column, let's break down the expressions and evaluate them step by step.

1. 72 - (24 + 26) - In this expression, we have a subtraction operation inside parentheses. According to the order of operations (PEMDAS/BODMAS), we need to perform the addition operation first, and then subtract the result from 72. - Evaluating the expression: 72 - (24 + 26) = 72 - 50 = 22

2. (72 - 24) - 26 - In this expression, we have two subtraction operations. Again, following the order of operations, we perform the subtractions from left to right. - Evaluating the expression: (72 - 24) - 26 = 48 - 26 = 22

3. (48 + 49) - 39 - This expression involves addition and subtraction. We perform the addition first, and then subtract the result from 39. - Evaluating the expression: (48 + 49) - 39 = 97 - 39 = 58

4. 48 + (49 - 39) - In this expression, we have a subtraction operation inside parentheses. Following the order of operations, we perform the subtraction first, and then add the result to 48. - Evaluating the expression: 48 + (49 - 39) = 48 + 10 = 58

Comparison and Similarities

Comparing the examples, we can see that all four expressions yield the same result of 22. Therefore, the expressions are equal in terms of their final value.

However, the expressions differ in terms of the order of operations used. The first two expressions involve subtraction inside parentheses, while the last two expressions involve addition inside parentheses. The order in which the operations are performed may vary, but the final result remains the same.

It's important to note that parentheses are used to indicate the order of operations and can change the outcome of an expression. By using parentheses, we can control the sequence in which operations are performed.

Verifying the Sentence and Performing Calculations

To verify the sentence and perform the calculations, let's evaluate each expression:

1. 72 - (24 + 26) = 72 - 50 = 22 2. (72 - 24) - 26 = 48 - 26 = 22 3. (48 + 49) - 39 = 97 - 39 = 58 4. 48 + (49 - 39) = 48 + 10 = 58

As we can see, all the calculations have been performed correctly, and the sentence has been verified. The final results for the expressions are 22 and 58, respectively.
