You do the addition as in base 10 but whenever you reach 4, you "carry" 1.
So 1230 + 23 = 1253 = 1313 because in base 4, the 5 is equivalent to "1 and carry 1".

The decimal equivalent of 32 - 23 is 14 - 11. This is equal to 3 in both base 4 and decimal.
23/4 plus 1/4 = 6
8x8x8x8 = 84 = (23)4 = 23*4 = 212
I would convert to base 10 , multiply and then convert back to base 6. 35 base 6 is 3 * 6 + 5 = 23 in base ten. 4 * 23 = 92 which is 2*36 + 3* 6 + 2 , in base 6 , the answer is 232 .
Depends on the shape of the base of the pramid. Add the vertices of the base and add one. For example, the pyramids in Egypt have a square base. 4+1 = 5 vertices
