    17 - 2 * 3 - 8 = 3 ⇒ (-, *, - )

    Step-by-step explanation:

    Lets revise the order of operation

    # Multiplication and Division which comes first from left to right

    # Addition and Subtraction which comes first from left to right

    Lets explain how to solve the problem

    17 __ 2 __ 3 __ 8 = 3

    We want to use +, -, * or : symbols to make the statement true

    Lets try to find the correct operations

    ∵ The answer is smaller than all the numbers in the statement

    ∴ There is subtraction

    ∵ 17 - 2 = 15

    ∵ 15 - 3 = 12

    ∵ 12 - 8 = 4 which is not the answer

    Then lets multiply 17, 2 and multiply 3, 8 and subtract their results

    ∵ 17 * 2 = 34

    ∵ 3 * 8 = 24

    ∵ 34 - 24 = 10 which is not the answer

    Then lets multiply 2, 3 and then subtract the result from 17 and then

    subtract 8 from the last result

    ∵ 2 * 3 = 6

    ∵ 17 - 6 = 11

    ∵ 11 - 8 = 3 which is the answer

    ∴ 17 - 2 * 3 - 8 = 3

    ∴ The symbols are -, *, -

    17-2*3-8=3

    Step-by-step explanation:

    We have given:

    17_2_3_8=3 insert + - * or : symbols to make each statement true ?

    Solution:

    We will insert multiplication sign between 2 and 3 and then subtract all the terms

    17-2*3-8=3

    We will solve it according to the DMAS rule:

    DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction. Without DMAS rule all mathematical equations will come up with different answers.

    Lets solve the expression and check whether the L. H. S = R. H. S

    17-2*3-8=3

    17-6-8=3

    11-8=3

    3 = 3

    Be sure to multiply first and then subtract

    ⇒You can also insert addition sign in place of multiplication. It will give the same answer
