wish of those help This isn't implicit multiplication, but use of the unary - operator.

I wish this help you Using the Decimal.Multiply will force the multiply to take inputs of type decimal instead of whatever the type that is being used and converted to decimal.
Decimal.Multiply(decimal d1, decimal d2) and will enforce and output of type decimal. Where as the * you could do:
code :
``````decimal result = yourDecimal * yourInt;

Does that help Why not just put the operation in the SQL update query ?
For example, you could have a query such as this one :
code :
``````UPDATE items SET quantity = quantity - 1 WHERE item_id = '\$id'
``````
``````UPDATE items SET quantity = quantity + 1 WHERE item_id = '\$id'

I wish did fix the issue. A string is returned from prompt when user clicks OK and null if cancel is clicked. So concatenation of two string that is "7" + "7" is "77".Use parseInt or Number constructor to convert string to number before addition
code :
``````var a = prompt("Please enter a number");
var b = prompt("Please enter a number");
console.log(typeof a, typeof b)

let sum = parseInt(a, 10) + parseInt(b, 10);
console.log(sum)``````
