For me, I do:
7 + 9 = 16 (which further breaks down into 9 + 1 = 10, 10 + 6 = 16, but we’ll ignore that)
20 + 80 = 100
100 + 16 = 116
How about you?
Just have a cry

Adding an extra one! Madness!
Can do maths in my head very well but usually only if it’s prices. Ask me what 287+1562 is and not a clue but £2.87+£15.62? Easy.
I’ve gone cross-eyed trying to do this in my head

Easier to round up the nearest one to a round number then work downwards I find.
200 + 800 = 1000
70 + 90 = 160
1000 - 160 = 840
Remove the zero = 84
84
