Software for writing math

I have developed super lazy eyeballing habit and I never really calculate anything

First time for years and last time I did do actual math was with

[Guide] About RAM, CAS & refresh rate

What is Ram / Memory Refresh? Dynamic Random Access Memory, DRAM for short as is used in computers is a form of volatile memory and therefore is prone to loosing it's information when unpowered. What you may not know however is exactly how DRAM is powered in the first place and how does it store information electrically? DRAM is effectively in general terms best described as a very large bank of capacitors arranged in rows and columns. Each capacitor is known as a cell. Depending on the charge retained in the cell we are able to determine if that cell is storing a 1 or a 0. A bit if you will. Unfortunately capacitors have this annoying property of loosing their charge over time due to various thermodynamic and other effects, these get worse the smaller or warmer the capacitors cells become Sidenote: Cooling your RAM down to very low temperatures is a great trick to retaining the charge in the memory cells for longer. Now due to this problem of capacitors in DRAM loosing their charge we need to top up this charge from time to time in order to avoid loosing the state of the bit in that cell. This is what we call Memory Refresh. Memory refresh is the process of periodically reading information from an area of computer memory and immediately rewriting the read information to the same area without modification, for the purpose of preserving the information. This process is carried out periodically by the memory circuitry all the time in the background. The interval or period of how often this occurs is known as the tREF in most BIOS menus. The time it takes for it to complete a Refresh is what we refer to as the Refresh Cycle. Commonly called tRFC in the BIOS menu's you may have seen. Both these values are usually measured in number of clock cycles. | Refresh Period | | Refresh Cycle | Access | Access | Access | Access | Access | <--|---------------------|--------|--------|--------|--…

and I honestly couldnt do it first, and it took 12 hours for my unused muscles warm up a bit and then I literally woke up with the answers in my head

and just writing down stuff and pulling nodes to places would be so much more my lazy af way
