Question

(23,82+54,58)·(1,202+0,698)-2,1·(3,55-1,89)=?

Answer 1

1) 23,82 +54,58=78,4
2)1,202+0,698=1,9
3)3,55-1,89=1,66
4)78,4*1,9=148,96
5)2,1*1,66=3,486
6)148,96-3,486=145,474

Answer 2

78,4*1,9-2,1*1,66=145,474

Answer 3

Let's solve the expression step by step:

Step 1: Add the two numbers inside the first parentheses: 23.82 + 54.58 = 78.4 Step 2: Add the two numbers inside the second parentheses: 1.202 + 0.698 = 1.9 Step 3: Multiply the results of Step 1 and Step 2: 78.4 * 1.9 = 148.96 Step 4: Subtract the two numbers inside the third parentheses: 3.55 - 1.89 = 1.66 Step 5: Multiply the result of Step 4 by 2.1: 1.66 * 2.1 = 3.486

Now, the final calculation is: 148.96 - 3.486 = 145.474

So, (23.82 + 54.58) * (1.202 + 0.698) - 2.1 * (3.55 - 1.89) = 145.474
