Cross-Multiplication
Multiply 2-digit numbers in one pass — left to right.
23 × 12 = 276
The long way is two rows. The shortcut reads the three columns.
Hundreds from the left pair, units from the right — and the tens are the CROSS.
Read it off left to right: 276. When a part spills past nine, carry it.
