In a world dominated by numbers it is important that everyone can make sense of the issues that affect us all: the economy, climate change, health.  This typically does not require precise calculations (arithmetic), nor abstract algebra (mathematics), but sits somewhere in between.  When you are filing a bowl of water, you know to reduce the flow form the tap as the bowl nears its top – this is is precisely a qualitative understanding (slower flow => slower filling) of a quantitative phenomena (exact flow rates and volumes).
