pls someone explain How to left shift this number ? 1010110<<2 Answer 1: shifting to the left means adding extra 0's as rightmost bits so in this case it means 101011000 now digit will be 1011000 but 1010110 represents 86 in decimal and left shift by 2 means multiply with 4 to the decimal number and now result 344 =101011000 now m confused ?
