@ -35,7 +35,7 @@ An alternative algorithm to implement multiplication using only:
# Algorithm
1. Initialize Sum <- zero. In C nomenclature: `Sum = 0;`
2. If B is odd then add A to Sum. In C nomenclature: `Sum += A;`
2. If B is odd then add A to Sum. In C nomenclature: `if( B & 1 ) Sum += A;`
3. Multiply A by 2 -- that is, Shift A **left** by one. In C nomenclature: `A <<= 1;`
4. Divide B by 2 -- that is, Shift B **right** by one. In C nomenclature: ` B >>= 1;`
5. If B is zero then STOP. `while( b ) { ... }`
