Question

(11-10,2171+11-7,87+0,07*05+2,746+1,52+3,89-6,7*0,5)+(7-6,5)

Answer 1

11-10.2171=0.7829
0.7829+11=11.7829
11.7829-7.87=3.9129
0.07*0.5=0.035
3.9129+0.035=3.9479
3.9479+2.746=6.6939
6.6939+1.52=8.2139
8.2139+3.89=12.1039
6.7*0.5=3.35
12.1039-3.35=8.7539
7-6.5=0.5
8.7539+0.5=9.2539

Answer 3

Let's break down and solve the expression step by step:

Step 1: Perform the operations inside the parentheses first.

1. 11 - 10 = 1
2. 2171 + 11 = 2182
3. 7 - 87 = -80
4. 0.07 * 05 = 0.07 * 5 = 0.35
5. 2.746 + 1.52 + 3.89 = 8.156
6. 6.7 * 0.5 = 3.35

Now, let's replace these results in the expression:

(1 + 2182 - 80 + 0.35 + 8.156 - 3.35) + (7 - 6.5)

Step 2: Continue with the operations inside the parentheses.

1. 1 + 2182 - 80 + 0.35 + 8.156 - 3.35 = 2108.156

Replace this result in the expression:

2108.156 + (7 - 6.5)

Step 3: Perform the operation inside the parentheses.

7 - 6.5 = 0.5

Replace this result in the expression:

2108.156 + 0.5

Step 4: Finally, perform the addition:

2108.156 + 0.5 = 2108.656

So, the result of the expression is approximately 2108.656.
