To prove that 2k 2k plus 1-1 by induction is a step by step process. But the induction 2 is not equal to 2 to the power of 0 take away 1.
Is the following what you are claiming? 2k = 2k+1 -1 20 not equal 20+1 - 1 21 not equal 21+1 -1
1 plus 1 equal = 2
1+1 or 1 plus 1 is equal to 2.
When you are using non-standard definitions of "plus" and "minus", or of "equal".
It isn't equal, and any proof that they are equal is flawed.
1 plus negative 10 is equal to -9.
it equal 18 (eight- teen)
this is clearly a trick question. 20 plus 20 plus 20 is equal to 60 and there is 60 minites in 1 whole hour so 20 plus 20 plus 20 is equal to 1.
6666 - 3212 - 3234 = 220
