Calculating Expressions:

Let's calculate the given expressions step by step:

1. (1250-1125)*3 + 125*100 First, we calculate the value inside the parentheses: `(1250-1125)*3 = 125*3 = 375` Then, we calculate the second part of the expression: `125*100 = 12500` Adding both results together: `375 + 12500 = 12875`

2. 1250 + 7500:5 + 2530

We start by performing the division: `7500 ÷ 5 = 1500` Then, we add the results together: `1250 + 1500 + 2530 = 5280`

3. (10500-7050):10 + 75

First, we calculate the value inside the parentheses: `(10500-7050) ÷ 10 = 3450 ÷ 10 = 345` Then, we add the second part of the expression: `345 + 75 = 420`

4. 20450-20405 + 2145

We start by subtracting the first two numbers: `20450 - 20405 = 45` Then, we add the third number: `45 + 2145 = 2190`

5. 38000 + 95*200 - 3700

First, we calculate the multiplication: `95*200 = 19000` Then, we add the first and second numbers and subtract the third number: `38000 + 19000 - 3700 = 53300`

6. 5700*(32*50-4*400)

First, we calculate the values inside the parentheses: `32*50 = 1600` `4*400 = 1600` Then, we subtract the second value from the first: `1600 - 1600 = 0` Finally, we multiply the result by 5700: `0 * 5700 = 0`

So, the results of the given expressions are: 1. (1250-1125)*3 + 125*100 = 12875 2. 1250 + 7500:5 + 2530 = 5280 3. (10500-7050):10 + 75 = 420 4. 20450-20405 + 2145 = 2190 5. 38000 + 95*200 - 3700 = 53300 6. 5700*(32*50-4*400) = 0
