Answer 1

Answer:

13+43=56

-58

20

12

These are the answers.

Answer 2

${X}$Concept: BODMAS rule, Calculation of bodmas equation by using this this rule,

Given that:        (1) 13+43=___

                          (2) -13-45=___

                          (3) -23+43=___

                          (4) 13-4​=___

Solution:

• BODMAS means B for Brackets, O for Orders, D for Division, M for Multiplication, A for addition and S for subtraction.
• If we solving the BODMAS equation then we have to follow the step by step this rule.

In question (1),

      let,   ${X}$=13+43,

             ${X}$=56, (here we simply addition)

        then answer will be 56, for question (1),

In question (2),

       let,   ${Y}$= -13-45

               ${Y}$= (-13)+(-45) (simply addition in two negative value)

               ${Y}$=-58,

        then answer will be -58 for question (2)

In question (3),

  let, ${Z}$= -23+43

         ${Z}$=43-23 (we can write for easy to simplify)

            ${Z}$=20

    then answer will be 20 for question

In question (4),

     let, ${Q}$=13-4

            ${Q}$=9 (simply here we subtraction)

   then answer will be 9 for question (4)

Final answer: 56 for question (1), -58 for question (2), 20 for question (3), and 9 for question (4)
