−400:(−7−13+10)=
\( -400:(-7-13+10)= \)
\( -3.5:-7+14= \)
\( -(-7+4):(-9)= \)
\( -12:-6\cdot(-8+4)= \)
\( -7:-49:+14:(-3+2)= \)
First, let's solve the expression in parentheses from left to right:
Now the expression we have is:
Let's note that we are dividing two negative numbers, so the result must be a positive number:
Therefore:
Let's solve the exercise from left to right.
We'll write the division problem as a simple fraction in the following way:
Let's note that we are dividing a negative number by a negative number, so the result will necessarily be a positive number:
We'll break down 7 into a multiplication problem:
We'll reduce the 3.5 in both the numerator and denominator of the fraction and get:
