What is 548 × 4?

Explanation:
Multiplying by a single digit scales each part of the number. Break 548 into 500 + 40 + 8 and multiply each by 4: 4×500 = 2000, 4×40 = 160, 4×8 = 32. Add them up: 2000 + 160 + 32 = 2192. So 548 × 4 = 2192. You can also double twice: 548×2 = 1096, then 1096×2 = 2192. If you round to 550 and compute 550×4 = 2200, you’d subtract 2×4 = 8 to correct, yielding 2192.
