408*2=(400+8)*2=800+16=816

Answer 3

Let's break down the equation step by step:

1. $408 \times 2 = 816$
2. $400 + ???$ (We need to find ??? that, when added to 400, gives us 816)
3. $??? + ??? = ???$ (We need to find two numbers that add up to 816)

To find the missing values:

2. $400 + ??? = 816$ Subtract 400 from both sides: $??? = 816 - 400 = 416$

3. $??? + ??? = ???$ Since we already found that ??? equals 416, the equation becomes: $416 + ??? = 816$ Subtract 416 from both sides: $??? = 816 - 416 = 400$

So, the complete equation is: $408 \times 2 = (400 + 416) \times 2 = 400 + 416 = 816$
