「加減乘除基金 (Agent of Change Foundation)」為成立於2015年之註冊慈善組織及香港社會服務聯會會員，主要服務除向基層提供價廉物美的日用品外，更希望超越社福圈子的限制，期望透過機構的三個專注領域：人本社區，藝術體驗及科技應用，配合跨界別合作和物資支援，成為社會推動議題改變的引擎。 Founded in 2015, Agent of Change Foundation is conceived with the mission of providing quality everyday necessities at a reasonable price to grassroot communities. Today, we operate with an additional mandate of driving collective discussions on social issues through the three main focus areas of the organization: technology, art, and community/people.
