the ammunition would be the 25-20 Winchester center fire (25-20 WCF). ammunition is still manufactured by Winchester for this rifle.
To calculate 25 times 25, you can use multiplication. One way to do this is to set it up as 25 x 25. You can also break it down: 25 can be thought of as (20 + 5), so you can use the distributive property: (20 + 5) x (20 + 5) = 400 + 100 + 100 + 25 = 625. Thus, 25 times 25 equals 625.
It depends on the type of ports needed. If you need more USB sockets, you can simply plug a USB hub into a USB socket. However, if you need other types of ports (like display ports, network ports, 9 or 25-pin serial ports, SATA sockets etc)., or you don't want to use a USB hub, then you would have to install an expansion card.
Parallel ports typically have 25 or 36 pin ports. Serial ports, by contrast, have only 9 pins. Both type of ports have two rows of pins.
20% of 25 = 20% * 25 = 0.2 * 25 = 5
25% off of 20 = 15= 25% discount applied to 20= 20 - (25% * 20)= 20 - (0.25 * 20)= 20 - 5= 15
25% off of 20 = 15= 25% discount applied to 20= 20 - (25% * 20)= 20 - (0.25 * 20)= 20 - 5= 15
Not sure that it is worth the effort for this multiplication, but 5*25 = 5*(20 + 5) = 5*20 + 5*5 = 100 + 25 = 125
There are 25 sea ports on the Black Sea, the Danube/Black Sea Canal and on the Danube River. On the Black Sea, for example, are the ports of Constanta, Mangalia, Midia and Sulina
20 x 25 = 500
[(25 - 20)/20]100 = 500/20 = 25%
