Answer 2

a) To find the value of 560×180-880×56, we can follow the order of operations, which is multiplication first and then subtraction.

First, let's calculate 560×180: 560×180 = 100,800.

Next, let's calculate 880×56: 880×56 = 49,280.

Now, let's subtract the second result from the first: 100,800 - 49,280 = 51,520.

Therefore, the value of 560×180-880×56 is 51,520.

b) To find the value of 45×40-40×25, we can again follow the order of operations.

First, let's calculate 45×40: 45×40 = 1,800.

Next, let's calculate 40×25: 40×25 = 1,000.

Now, let's subtract the second result from the first: 1,800 - 1,000 = 800.

Therefore, the value of 45×40-40×25 is 800.

c) To find the value of 490×730-73×900, we'll follow the same steps.

First, let's calculate 490×730: 490×730 = 358,700.

Next, let's calculate 73×900: 73×900 = 65,700.

Now, let's subtract the second result from the first: 358,700 - 65,700 = 293,000.

Therefore, the value of 490×730-73×900 is 293,000.

d) Finally, to find the value of 36×3400-360×140, we'll follow the same steps.

First, let's calculate 36×3400: 36×3400 = 122,400.

Next, let's calculate 360×140: 360×140 = 50,400.

Now, let's subtract the second result from the first: 122,400 - 50,400 = 72,000.

Therefore, the value of 36×3400-360×140 is 72,000.

In summary: a) 560×180-880×56 = 51,520. b) 45×40-40×25 = 800. c) 490×730-73×900 = 293,000. d) 36×3400-360×140 = 72,000.
