Answer (1)

Let's solve each of the operations step-by-step:
1. Addition: The numbers to add are:
987539 + 345210345678 + 346710
First, add 987539 and 346710:
987539 + 346710 = 1334249
Next, add that sum to 345210345678:
1334249 + 345210345678 = 345211679927
So, the total sum is 345211679927 .
2. Subtraction: The numbers to subtract are:
984321 − 8732054673 − 46321
First, subtract 8732054673 from 984321:
984321 − 8732054673 = − 8731070352
Then, subtract 46321 from this result:
− 8731070352 − 46321 = − 8731116673
So, the final result of the subtraction is − 8731116673 .
3. Multiplication: The numbers to multiply are:
3214 × 3454563 × 212
First, multiply 3214 and 3454563:
3214 × 3454563 = 11107412742
Next, multiply this result by 212:
11107412742 × 212 = 2354791513304
So, the final result of the multiplication is 2354791513304 .
4. Division: The numbers to divide are:
42224 ÷ 1234521 ÷ 15
First, divide 42224 by 1234521:
Since 42224 is much smaller than 1234521, 1234521 42224 ​ ≈ 0.0342 .
Now, divide this result by 15:
0.0342 ÷ 15 = 0.00228 (rounded to five decimal places)
So, the final result of the division is approximately 0.00228 .
Each operation involves simple step-by-step calculations according to standard arithmetic rules.
