You could break down the corresponding elements. So you could add the 600 and the 200 giving 800. You could then add the 90 and the 2, giving 92. Then add the 800 and the 92, giving 892.
Mental math is basically math in your head so for example 40x2=80 so I did that in my head
50 what's "mental math" supposed to mean? if it just means you did it in your head, then there is no difference between mental and regular math, except that it is harder to check your work.

There are lots in math. Some are break apart and add on .
You take all the answers and add it all together. Break apart is a multiplication strategy. To multiply 45 and 6, you first break apart the 45 into 40 and 5, now multiply both with multiplier 6. Then add both of them. This is 40x6 + 5x6= 240 + 30 = 270
break means too pull a math question apart. (im not sure)

This is taught as a mental math strategy Typically you "break" each addend into tens and ones to solve 45 + 32 the students do this: For example: 45 "breaks into" 40 + 5 Similarly 32 "breaks into" 30 + 2 Students then add the tens 40 + 30 = 70 and then add the ones 5 + 2 = 7 and then add the two sums together 77 ...... 45 + 32 = 77
