Question

$19\times(20-4\times5)=$

00:00 Solve

00:03 Always solve parentheses first

00:06 Always solve multiplication and division before addition and subtraction

00:12 Let's calculate the parentheses

00:16 Any number multiplied by 0 always equals 0

00:19 And this is the solution to the question

First, we solve the exercise in the parentheses

$(20-4\times5)=$

According to the order of operations, we first multiply and then subtract:

$20-20=0$

Now we obtain the exercise:

$19\times0=0$
