Hii

How to add numbers mentally?

If your numbers are ending in zero u may simply change the digits acording the place value. Like, 700 + 8, 8 is in units so we willl simply change units place of 700 to 8 that is, 708.

For 2nd one, 4+6=10 so simply add 10 to 50 that is? 60! so 54+6 will equal 60.
