Question

(37000 - 7000) : 10 - 1560= 20000 + (68 x 7 + 2524= 56 x 5 x 100 - 20000= (78 : 3 x 8 + 3792) + 700000=

Answer 1

(37000 - 7000) : 10 - 1560= 30000 ÷ 10 - 1560 = 3000 - 1560 = 1440

20000 + (68 x 7 + 2524) = 20000 + (476 + 2524) = 20000 + 3000 = 23000

56 x 5 x 100 - 20000 = 280 × 100 - 20000 = 28000 - 20000 = 8000

(78 : 3 x 8 + 3792) + 700000 = (26 × 8 + 3792) + 700000 = (208 + 3792) + 700000 = 4000 + 700000 = 704000

Answer 2

Let's break down the given expression step by step:

1. $(37000 - 7000) \div 10 - 1560$ $= 3000 \div 10 - 1560$ $= 300 - 1560$ $= -1260$

2. $20000 + (68 \times 7 + 2524)$ $= 20000 + (476 + 2524)$ $= 20000 + 3000$ $= 23000$

3. $56 \times 5 \times 100 - 20000$ $= 280000 - 20000$ $= 260000$

4. $(78 \div 3 \times 8 + 3792) + 700000$ $= (26 \times 8 + 3792) + 700000$ $= (208 + 3792) + 700000$ $= 4000 + 700000$ $= 704000$

Now, the final expression is $-1260 + 23000 + 260000 + 704000$, which equals $991740$.
