Write the numbers 0,1,2,3,4,5,6,7,8,9 in this order and insert + or - between them to get the result -3

The order is ;

0+ 1 + 2-3+ 4 -5+6-7+ 8 - 9

Step-by-step explanation:

Here, we want to write the numbers in that order, inserting a subtraction or addition sign between them.

These are;

0+ 1 + 2-3+ 4 -5+6-7+ 8 - 9

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
