$600 + 420 = 1020$

Step1: Break into partial products

For $62 \times 56$:
$62 \times 50 = 3100$, $62 \times 6 = 372$

Step2: Sum partial products

$3100 + 372 = 3472$

Step1: Break into partial products

For $58 \times 46$:
$58 \times 40 = 2320$, $58 \times 6 = 348$

Step2: Sum partial products

$2320 + 348 = 2668$

Step1: Break into partial products

For $50 \times 17$:
$50 \times 10 = 500$, $50 \times 7 = 350$

Step2: Sum partial products

$500 + 350 = 850$

Step1: Break into partial products

For $59 \times 27$:
$59 \times 20 = 1180$, $59 \times 7 = 413$

Step2: Sum partial products

Step1: Break into partial products

For $60 \times 42$:
$60 \times 40 = 2400$, $60 \times 2 = 120$

Step2: Sum partial products

$2400 + 120 = 2520$

Step1: Break into partial products

For $42 \times 59$:
$42 \times 50 = 2100$, $42 \times 9 = 378$

Step2: Sum partial products

$2100 + 378 = 2478$

Step1: Multiply by tens and units

For $56 \times 20$:
$56 \times 2 \times 10 = 1120$

Step1: Break into partial products

For $88 \times 98$:
$88 \times 90 = 7920$, $88 \times 8 = 704$

Step2: Sum partial products

$7920 + 704 = 8624$

Step1: Break into partial products

For $96 \times 84$:
$96 \times 80 = 7680$, $96 \times 4 = 384$

Step2: Sum partial products
