提高 is written with 22 strokes (提: 12, 高: 10). The animation replays automatically.
提高 (tígāo) is a transitive verb meaning 'to raise / improve / lift to a higher level.'
It always takes an abstract object — a level, a score, an ability, a price, a standard: 提高水平 ('raise one's level'), 提高成绩 ('improve grades'), 提高效率 ('improve efficiency'). The two characters are literal: 提 'lift' + 高 'high' = lift higher. Key distinction from English: 提高 is for intangible things you can measure on a scale. You do NOT use it for picking up a physical object — that's 拿 (ná) or 举 (jǔ).
The opposite is 降低 (jiàngdī, 'lower / reduce'). A near-synonym is 提升 (tíshēng), which is slightly more formal and often used for promotions and quality. 提高 is the everyday workhorse word.

提升 is slightly more formal and often used for promotions at work (他被提升为经理) and elevating overall quality. 提高 is the everyday word for raising a number, level, or skill.
改善 means 'to make better / ameliorate,' used for conditions and situations (生活, 关系, 环境). 提高 is for things that move up a measurable scale (level, score, price).
增加 means 'to increase in quantity / add to.' Use 增加 for things you can count (人数, 收入); use 提高 for things you measure on a quality scale (水平, 效率).
提 alone has many meanings — to lift, to mention (提一下 'mention it'), to bring up (提问 'ask a question'). 提高 is specifically 'raise to a higher level.'
