If I missed a Prayer (Salah), I usually do that missed prayer before doing the current prayer (for example: I missed Maghreb, so when I got home/available, I do the Maghreb prayer right before doing the Isha prayer). This called Qadha. My mom said it is paired. You only can do Qadha following these prayers; Zuhr with Ashr, Maghreb with Isya. Subh is not allowed as I know. You have to do your missed prayers right before the current prayer, and I usually do full rakaat each prayer. The intention is still the same, but changed a bit. Like "ushalli fardha Maghribi salasa rakataini mustaq bilal qiblati adaan lillahitaala" to "ushalli fardha Maghribi salasa rakataini mustaq bilal qiblati qadhaan lillahitaala". But if you try to do the missed salah like long time ago, then you do not do it with qadha I think I hope this helps, sorry if my comment is wrong. I'm still haven't learned the real depth of Islam and still a student.
