I better clarify:
(MBA + AI) - AI
= (MBA + AI) + (-AI)
= MBA + [AI + (-AI)]
= MBA + 0
= MBA
Note that the associative property is not applied to the subtraction operation here.

False. The only operation involved here is addition because the subtraction operation is defined as adding to something the additive inverse of something else. Hence, the OP correctly applied the AP.
Submission + - NLNet funds development of a Libre RISC-V 3D CPU (crowdsupply.com)
lkcl writes: The NLNet Foundation has approved funding for the Hybrid Libre RISC-V CPU/VPU/GPU under its Privacy and Enhanced Trust Programme. High security software is irrelevant if the hardware is fundamentally compromised, for example with the Intel spying backdoor co-processor known as the Management Engine. The Libre RISCV SoC was begun as a way for users to regain trust and ownership of the hardware that they legitimately purchase.
This processor will be the first of its kind, as the first commercial SoC designed to give users the hardware and software source code of the 3D GPU, Video Decoder, main processor, boot process and the OS.
Shockingly, in the year 2019, whilst there are dozens of SoCs with full source code that are missing either a VPU or a GPU (such as the TI OMAP Series and Xilinx ZYNQ7000s), there does not exist a single commercial embedded SoC which has full source code for the bootloader, CPU, VPU and GPU. The iMX6 for example has etnaviv support for its GPU however the VPU is proprietary, and all of Rockchip and Allwinner's offerings use either MALI or PowerVR yet their VPUs have full source (reverse engineered in the case of Allwinner).
This processor, which will be quad core dual issue 800mhz RV64GC and capable of running full GNU/Linux SMP OSes, with 720p video playback and embedded level 25fps 3D performance in around 2.5 watts at 28nm, is designed to address that imbalance. Links and details on the Libre RISC-V SoC wiki.
The real question is: why is this project the only one of its kind, and why has no well funded existing Fabless Semiconductor Company tried something like this before? The benefits to businesses of having full source code are already well-known.

Submission + - EOMA68 Earth-friendly Modular computing campaign hits $50k (crowdsupply.com) 9
lkcl writes: The EOMA68 Crowd-funding campaign launched last month and has just reached $50,000 and so far has 541 backers with 28 days still to go. EOMA68 and its creator have featured regularly on slashdot over the past five years: a live-streamed video from Hope2016 explains what it's about, and there is a huge range of discussions and articles online. The real burning question is: if a single Software Libre Engineer can teach themselves PCB design and bring modular computing to people on the budget available from a single company, why are there not already a huge number of companies doing modular upgradeable hardware?
