Question

a
⁴56
× 2□
-----
¹392
+ 1,1□0
-----
1,512

Explanation:

Step1: Find the units digit of multiplier

Let the unknown units digit of the multiplier be $x$. We know $56 \times x = 392$. Solve for $x$:
$x = \frac{392}{56} = 7$

Step2: Find the tens digit in 1,1□0

Let the unknown tens digit be $y$. We know $392 + 11y0 = 1512$ (where $11y0$ represents $1100 + 10y$). Rearrange to solve for $11y0$:
$11y0 = 1512 - 392 = 1120$
So $y = 2$.

Step3: Verify the hundreds digit of 56

The 5 in 56 has an overline, meaning it is the tens digit of the product of $56 \times 20$ plus carryover? No, actually, the top gray square is the carryover from $56 \times 7$: $56 \times 7 = 392$, so the carryover to the hundreds place is 3.

Answer:

Top gray square: 3, units digit of multiplier: 7, tens digit in 1,1□0: 2
