The equation could be divided into three terms: 15x37, 15x6315x37 and 15x63. First, he could take the same multiple for all three. It would be 15. So,

15(37+6315x37+63)

Simplifying by applying PEMDAS. We calculate first the operation inside the parenthesis followed by multiplying it with 15.

15 (233755) = 3506325

Answer:

Step-by-step explanation:

Given that Dominique wants to find the value of the expression

15.37+15.63

He wants to do mentally using distributive property

Distributive property over multiplication is

[tex]a(b+c) = ab+ac[/tex]

Using this he can write

[tex]15.37+15.63\\=15(37+63)\\=15(100)\\=1500[/tex]

Thus he got answer very quickly in the mind itself as 1500
