Return to the chart or jump to how to find a part common to all kits or how to find parts common to two kits.
To see how many of a given part is included in all NXT kits, you will need to know which part you are looking for and follow these steps.
In this example, we will find out how many 7module long axles are in all the NXT sets

Every NXT owner has at least 4 of these.
Any NXT set with a resource kit will have at least 10 of these.

NXT 2.0  6  20  4  10  
NXT Edu  4  4  4  4

We see that every NXT contains at least 4 7module long axles.

To find out how many of a given piece you can count on two different kits having, you'll need to know which piece you are looking for, and what the two kits are you are checking on.
In this example, we will find out how many 7module long axles are sure to be in every NXT 2.0 kit and every NXT Education Base Set with Resource Kit.

We want to see what is in common between an NXT 2.0 kit and the combined NXT Education Base Set and Resource Kit, so we'll start with looking at the row for the NXT 2.0 kit.

The column marked "Edu + Rsc" is the one for the Education Base Set with a Resource Kit

32524  Technic Beam 7  ∩  NXT 1.0  NXT 2.0  NXT Edu  Edu + Rsc 
Every NXT owner has at least 4 of these.
Any NXT set with a resource kit will have at least 10 of these. 

NXT 1.0  6  6  4  6  
NXT 2.0  6  20  4  10  
NXT Edu  4  4  4  4  
Edu + Rsc  6  10  4  10 
In this case, the number is 10. That means that every owner of an NXT 2.0 kit and every owner of a combined NXT Education Base Set and Resource Kit will have 10 7module long axles (provided they haven't lost any!)
