Question

sub. [ -7 ] - [ -3 ]​

Answer 1

Answer:

∴ The value of $-7-(-3)$ is $-4$.

Step-by-step explanation:

In context to question asked,

• We have to subtract $-3$ from $-7$.
• Subtraction is one of the important arithmetic operation of mathematics among division, multiplication, addition and subtraction.
• In subtraction, if two numbers have different signs i.e. one positive number and other is negative number, then find the difference between them and put the sign of greater number.
• -ve $\times$ -ve = -ve
• Now,  the given expression is,

        $-7-(-3)=-7+3$

                      = $-4$

• ∴ The value of $-7-(-3)$ is $-4$.
