Answer 2

To calculate the expression (834×452×497+476-1307-2694×75468+244-7×49)÷20, we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

Let's break down the expression step by step:

First, let's evaluate the multiplication operations: (834 × 452 × 497) = 186,541,656

Next, we calculate the multiplication: (2694 × 75468) = 203,425,992

Now, let's simplify the expression further: (186,541,656 + 476 - 1307 - 203,425,992 + 244 - 7 × 49)

Multiplying 7 by 49, we get: (186,541,656 + 476 - 1307 - 203,425,992 + 244 - 343)

Combining the numbers: (186,541,656 + 476 - 1307 - 203,425,992 + 244 - 343) = 186,408,734

Finally, we perform the division operation: (186,408,734 ÷ 20) = 9,320,436.7

Therefore, the value of the given expression is approximately 9,320,436.7.
