Answer:
-50
Step-by-step explanation:
Luckily for us this one is very simple.
(-5)(10) can also be written as [tex]-5*10[/tex] or with any other multiplicative operator (a symbol that represents multiplication). So this becomes very simple multiplication.
We know that when we multiply a positive number by a negative, the result will be negative - and we also know that 5 times 10 is 50. So our result will be: [tex](-5)(10) = -50[/tex]
