Google Adwords traffic shows a different level to Google Trends

[mblsolutions]

Hello I am doing some keyword research support for a client. The keywords that we are looking at Keyword A is 880 LMS and Keyword B is 2900 LMS through Google Adwords. When we look at Google Trends Keyword A is showing much high traffic than keyword B. Does anyone know why this is?

Many thanks

I searched these terms and I'm not sure what they mean. Can you provide some clarification?

In  my results it shows that 880 LMS is associated to Mobius Learning Centers, which would likely have more search traffic than a part number for 2900 LMS. More information would be very useful here. Thanks!
