Question

1863:23*11-2 (3885:37+245)*78

Answer 1

1863÷23×11-2=889
(3885÷37+245)78=27300

Answer 2

Let's break down the expression step by step:

1. 23 * 11 = 253
2. 3885 / 37 = 105
3. 105 + 245 = 350
4. 350 * 78 = 27,300

Now let's substitute the values back into the original expression:

1863:253 - 2 * 27,300

Using the colon (:) as a division symbol, we can simplify the expression:

1863 / 253 - 2 * 27,300

Finally, let's calculate the expression:

1863 / 253 ≈ 7.36322869955 2 * 27,300 = 54,600

So, the result is approximately:

7.36322869955 - 54,600 ≈ -54,592.6368
