=50*50/50*50+50/50-(50/50)
In Excel, Google, and Bing it is 2500.
Using PEMDAS:
50 * 50 / 50 * 50 + 50 / 50 - ( 50 / 50 ) [scan; P found; evaluate inside of P]
50 * 50 / 50 * 50 + 50 / 50 - ( 50 / 50 ) [scan inside P; D found; evaluate L->R; rescan]
50 * 50 / 50 * 50 + 50 / 50 - ( 1 ) [scan; no PEMDAS found; remove parenthesis; rescan]
50 * 50 / 50 * 50 + 50 / 50 - 1 [M found; evaluate L-R; rescan]
2500 / 50 * 50 + 50 / 50 - 1 [D found; evaluate L->R; rescan]
50 * 50 + 50 / 50 - 1 [M found; evaluate L-> R; rescan]
2500 + 50 / 50 - 1 [D found; evaluate L->R; rescan]
2500 + 1 - 1 [A found; evaluate L -> rescan]
2501 - 1 [S found; evaluate L->R; rescan]
2500
