Answer:
-30 x -13 = 390
Step-by-step explanation:
To multiply -30 and -13, just multiply them like how you multiply numbers without the negative or minus sign (-)
Remove the negative signs on both numbers then multiply.
The solution is 30 x 13 = 390
There is no more minus sign in the product, which is 390
You must also use a calculator to ensure the answer is right.
Use the +/- button in the calculator to add the negative sign before the number. so -30 x -13 equals 390
(A positive number permanently has no plus sign)
The answer is 390
Hope it helps :D
