Using the multiplication sign(x) One day mum went to the market and bought 3 baskets of apples 2 2 2 Mum asked me to tell her the total numbers of apples

So I add: 2 + 2 + 2 Then I noticed that 2 is repeated 3 times But mum told me that we had another 3 baskets of apples so now we have 6 baskets of apples 2 2 2 2 2 2 Mum asked me to tell her the total number of apples we had

So I add: 2 + 2 + 2 + 2 + 2 + 2 But I noticed this time that 2 is Repeated 6 times and it was difficult For me

You know guys in maths we have another easier Operation In previous example which was 2 + 2 + 2 + 2 + 2 + 2 Here 2 is repeated 6 times,we can write it as 2 x 6 So in math instead of repeating the number many times we can use the multiplication sign(x)
