Beltmatic - base 10 machine - 7 & 5 digits

Base 10 machine for making 7 digit numbers and 5 digit numbers in Beltmatic game.
Beltmatic is a nice game where you need to deliver numbers to a collector. To achieve this there are operators (adder, subtractor, multiplier, etc).
The game use prime numbers to make it difficult to combine operator, so this machine simple lets you select whatever number you want.
You can select a number for 0 to 9 for each digit, and you have 7 digits in one machine and 5 digits in the other. It is also plausible to combine both machines to get a 12 digit number by simple using the output of one machine in the input on the other (and modifing exponentiators)
To construct this machine you need to level up to obtain the exponentiator operator.
I like Beltmatic, but it could be heavely improved by adding logic gates, more objectives, some constraints (ie. cost in construction), switches, etc.

I feel like I just turned on cheatcodes due to a meme. Wow. You can just make lots of 2^n belts, have a combiner, and then just set up the binary. But this is a step further! Wild!

In fact binary machines is much easier than decimal ones.

[@AMS17121982]

Basically you need only 1 and 2 extractors, adders, and multipliers to beat the game. (No, you don't need exponentiators)

So basically you take every number and multiply it by 10 as much as needed for example
1245=1000*1+100*2+10*4+5.
How can i find a tutorial or a reference to make this,i dont want to mess up end waste hours for notthing

You nailed it, that's how it works.
The basic part is: ADDER -> EXPONENTIATOR -> MULTIPLIER -> ADDER
The first 3 parts generates the numer (ie 200 in your example), then the last adder adds this to the previous number (45 in your example)
The basic part is repeated a lot of times to make the machine fast.
