Question

2+49•64+67-56•777+666+8968-969

Answer 1

2+3136+67-43512+666+8968-969=-31642

Answer 2

To calculate the expression 2 + 49 × 64 + 67 - 56 × 777 + 666 + 8968 - 969, we need to follow the order of operations (also known as PEMDAS/BODMAS).

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

BODMAS is the same as PEMDAS but with "Brackets" instead of "Parentheses."

Let's calculate it step by step:

First, perform the multiplication:

49 × 64 = 3136

56 × 777 = 43512

Now we substitute the multiplication results back into the expression:

2 + 3136 + 67 - 43512 + 666 + 8968 - 969

Next, perform the addition and subtraction from left to right:

2 + 3136 = 3138

3138 + 67 = 3205

3205 - 43512 = -40307

-40307 + 666 = -39641

-39641 + 8968 = -30673

-30673 - 969 = -31642

Therefore, the value of the expression 2 + 49 × 64 + 67 - 56 × 777 + 666 + 8968 - 969 is -31,642.
