Explanation	Calculations	Help
$We subtract 32 from ten raised to the thirty-second power, which causes a chain of borrowings. The result has thirty nines, then a 6 and an 8.$	$m = 1 0^{32} - 32 = 99999...9968$	Theory & Tactics Method Card ALG6-A Click to view full details
$We then sum these digits by adding thirty 9s, 6, and 8.$	$sum of digits = 30 \times 9 + 6 + 8 = 270 + 14 = 284$
