The Return of Mathematics

I had made my peace with mathematics a long time ago. Or so I believed. By the time I sat for the police entry exam, mathematics had become, in my mind, a closed chapter, something I had wrestled with at Grade 12 during WASSCE, passed by whatever combination of preparation and mercy gets a student through that exam, and then quietly filed away as a subject other people needed, not me. I was a teacher of Civic Education. My world was constitutions and rights and duties, not equations. I had not touched an algebraic expression in years, had not needed to, had built an entire adult life on the comfortable assumption that numbers and I had already said our goodbyes.

The exam hall did not know any of this about me, of course. It simply handed out its paper the way it handed out papers to everyone in the room, and I sat down expecting what the recruitment notice had led me to expect; general knowledge, the kind of civic and current-affairs questions I could answer standing on one leg, questions about the country, its institutions, its history, the very material I had spent years teaching to children half my age. That part did not worry me. I moved through those sections with something close to confidence, the pen moving almost as quickly as the thoughts themselves.

Then I turned a page, and there it was. Mathematics had not been listed anywhere in my private expectations for that exam. I do not know why I had convinced myself of this perhaps because nobody had explicitly warned me, perhaps because I simply wanted it to be true but the effect of seeing those questions appear, uninvited, was almost physical. A fraction stared back at me from the page the way an old acquaintance stares back at you in a market you did not expect to see them in. An algebraic expression sat waiting to be simplified, patient and unbothered by how many years it had been since I had last simplified anything of the sort. Somewhere in that hall, my Grade 12 self reappeared beside me, the same anxious energy I remembered from WASSCE morning, sharpened pencil, checking the clock, wondering whether the formula I half-remembered was the right one or a cousin of the right one that would lead me astray.

I was not alone in this. I could feel it in the room, the particular quality of silence that comes not from concentration but from private panic being carefully hidden behind still faces. Around me, people who had likely walked in with the same assumption I had; general knowledge, nothing more were now bent over the same fractions, the same half-remembered rules for handling an equation, digging through memory for a formula that had been left dormant since secondary school. It was, in its own way, a great leveler. Whatever confidence any of us had walked in with regarding "easy" questions was now being tested against a subject none of us had prepared to meet again.

I did what I imagine most of the room did in that moment. I tried to reconstruct, piece by piece, whatever fragments of Grade 12 mathematics remained somewhere in me, the order of operations, the handling of a fraction, the patient unpacking of an algebraic term into something simpler. Some of it returned, slowly, like a language you have not spoken in years but can still stumble through when forced. Some of it did not return at all, and I moved past those questions the way you step past an obstacle you cannot lift, hoping the rest of the paper would be kind enough to make up the difference.

When I finally set my pen down and handed in my paper, I did not walk out of that hall with the clean confidence I had walked in with during the general knowledge section. I walked out genuinely unsure, turning the exam over in my mind the way I had turned over that plastic bag holding my form days earlier, wondering whether what was inside would be enough. I could not tell you, standing outside that hall afterward among the same quiet, uncertain faces I had sat beside inside it, whether I had done enough to pass. I only knew that mathematics, which I had long ago declared finished with me, had reminded me, one final time, on a page I had not expected it on that some subjects do not care whether you have moved on from them. They simply wait for the day you assume they are gone, and reappear exactly then.
