+52 Compute 4392_11 - 14A3 + 13A_11. Give your answer as a base 11 integer.
I got 685 and 1205 so far but both are wrong pls help
+129895 I assume the 14A3 is also base 11 ???
A =10
If so
439211 = 4(11)^3 + 3(11)^2 + 9 (11) + 2 = 578810
14A311 = (11)^3 + 4(11)^2 + 10(11) + 3 = 192810
13A11 = 1(11)^2 + 3(11) + 10 = 16410
5788 - 1928 + 164 = 402410
To convert back to base 11
4024 / 11 = 365 R 9
365 / 11 = 33 R 2
33/11 = 3 R 0
3/11 = 0 R 3
So
402410 = 302911
