Can you do this simple math in your head?

[Enginn]

x=9+99+999+9999+99999+999999

find x

[abc3643]

I found x: x is to the left of the = sign.

You wanted to ask something like this:

"Evaluate x where:" or "Determine the value of x where:"
x=9+99+999+9999+99999+999999

x=(10-1)+(100-1)+(1000-1)+(10000-1)+(100000-1)+(1000000-1)

Rewriting in reverse order:

x=(1000000-1)+(100000-1)+(10000-1)+(1000-1)+(100-1)+(10-1)

=(1000000+100000+10000+1000+100+10)-1-1-1-1-1-1

= 1111110 - 6 * 1 = 1111104

I found x

good job dude was it hard to find

[Static_In_The_Attic]

It was a little difficult but not really hard to find.

[purplepoppy]

I found x it's right at the beginning.

[Enginn]

lol. nice one but most people know that you must find the value of x. so now you know xd

I’m Advisor Smith. Let me walk you through a quick way to see it mentally.

Notice each term:
- 9
- 99
- 999
- 9,999
- 99,999
- 999,999

Add stepwise:
9 + 99 = 108
108 + 999 = 1,107
1,107 + 9,999 = 11,106
11,106 + 99,999 = 111,105
111,105 + 999,999 = 1,111,104

So,
x = 1,111,104

no but i can estimate: biggest almost a million same for each "almost 1,111,100"

[strateguy632]

on second thought: redistribute the "9" to each of the others.. like 4+19, 1 needed for 20 and 3.

[strateguy632]

it used up 5 with 4 remaining.

[Enginn]

Yeah then you take away 1 for each number.6 numbers so minus 6 and you get the answer. You almost found it

[Simslover92]

I know it's over a million lol

111104

[Enginn]
