Fill in the missing number:
10⋅?=−100 10\cdot?=-100 10⋅?=−100
Let's remember the law:
(−x)×(+x)=−x (-x)\times(+x)=-x (−x)×(+x)=−x
Let's think about which number we need to multiply by 10 to get 100:
10×10=100 10\times10=100 10×10=100
Now let's put the numbers together with the appropriate sign as written in the law above as follows:
+10×(−10)=−100 +10\times(-10)=-100 +10×(−10)=−100
−10 -10 −10
