Sue Fraser on Instagram: "Inverse means opposite. When children can see the maths using cubes, the concept becomes clearer and their confidence grows. This supports understanding, not just remembering a rule. 5+2=7 or 2+5=7 so 7-2=5 and 7-5=2 Always secure this with small numbers first 😊 #tutoryourchild #mathstutoring #homelearninguk #homelearning #mathsconfidence #primarymaths #homelearningideas #helpingmums #hometuitions #hometutor #inverse #addition #subtraction"
