Multiply the following binary numbers.
1010   1011   1001
×0011   ×0111   ×1010

A 0001  1110    0100  1101    0101  1011

B 0001  1110    0100  1100    0101  1010

C 0001  1110    0100  1101    0101  1010

D 0001  1101    0100  1101    0101  1010

ANS:C - 0001  1110    0100  1101    0101  1010

0b1010 = 0xA.
0b0011 = 0x3.
0xA * 0x3 = 0x1E = 0b00011110.

0b1011 = 0xB.
0b0111 = 0x7.
0xB * 0x7 = 0x4D = 0b01001101.

0b1001 = 0x9.
0b1010 = 0xA.
0x9 * 0xA = 0x5A = 0b01011010.
