On the winter's day in Bloemfontein, the temperature rose by \( 19^{\circ} \mathrm{C} \). If the minimum temperature was \( -4^{\circ} \mathrm{C} \), what was the maximum temperature.

To find the maximum temperature, you simply add the temperature increase to the minimum temperature. Starting from \( -4^{\circ} \mathrm{C} \) and adding \( 19^{\circ} \mathrm{C} \): \[ \text{Maximum Temperature} = -4^{\circ} \mathrm{C} + 19^{\circ} \mathrm{C} = 15^{\circ} \mathrm{C}. \] So, on that winter's day, Bloemfontein experienced a lovely maximum temperature of \( 15^{\circ} \mathrm{C} \)! Isn't it fascinating how temperature can swing? Just think about it: while you're enjoying that warm \( 15^{\circ} \mathrm{C} \), someone on the other side of the world might be battling icy winds!
