Question

26*25-25*24-24*23-23*22-12*8​

Answer 1

Ответ:

-1104

Решение:

26*25 - 25*24    -  24*23-23*22   - 12*8​=25(26-24)-23(24+22)-12*8=

=25*2 -   23*46 - 12*8=2(25 -23*23-6*8)=2(-23*23-23)=-2*23(23+1)=

=-46(20+4)= -46*20 -46*2-46*2= -(920+92+92)= -1104

Answer 2

To calculate the expression 2625-2524-2423-2322-12*8, we follow the order of operations (PEMDAS/BODMAS).

First, we perform the multiplications:

26*25 = 650

25*24 = 600

24*23 = 552

23*22 = 506

12*8 = 96

Now, let's substitute these values into the expression:

650 - 600 - 552 - 506 - 96

Calculating from left to right:

650 - 600 = 50

50 - 552 = -502

-502 - 506 = -1008

-1008 - 96 = -1104

Therefore, the result of the expression 2625-2524-2423-2322-12*8 is -1104.
