Just: “Acknowledge yourself , the fact that you know how to square double digit numbers ending with 5 only means that you are an expert compared to someone who still needs paper and calculator”

I am happy with the powerpoint slides.
Btw does that method work for only number ending with 5, cause l tried it with other numbers but fail to get correct answers.

Hi Gracious, the strategy works when you square number ending with ‘5′ for example 65 * 65 = ? , 85 * 85 = ?
To do this, it’s extremly easy,
#1: the answer will end with ‘25′
#2: take the first digit (6) x (multipy by) (1 more than 6 =7)
aka 6 * 7 = 42
so the answer is 4225
