How many tabs are in each window? ** The total number of tabs in three windows of each browser is 10*3 = <<10*3=30>>30 tabs.
How many tabs are in the two browsers together? ** If James had two browsers on his computer and in each browser he opened three windows, the total number of tabs in the two browsers is 2*30 = <<2*30=60>>60 tabs.
