hello neil,
think of it as three expressions

1) is 6 greater than 4? - TRUE
2) is 7 less than 5? - FALSE
3) what happens when you logically AND expression 1 with expression 2?
TRUE ANDed with FALSE EQUALS FALSE

remember that the order of operations is important!

Logical AND can be thought of as mathematical multiplication of 1's and 0's. 1 times 1 = 1, 1 times 0 = 0, no matter what! As he says, break it down. Remember BODMAS? Order is important,
in order,

BRACKETS, OF, DIVISION, MULTIPLICATION, ADDITION and finally SUBTRACTION.

This is the order to solve complex mathematical based questions such as the one above.
