Answer:
a) -64
0
b) 5
- 5
Step-by-step explanation:
Up square: Multiply the numbers in the right square and left square and write the answer in the up square.
Down square: Add the numbers in the right square and left square and write the answer in the down square.
Left and right square: Factorize the number in the up square and check if it satisfies (add or subtract the factors) the number in the down square.
a) Up square: -64
8*(-8) = -64
Down square: 0
8 + (-8) = 0
b) Factorize (-25), in such a way that when we add we should get 0.
-25 = 5 * (-5)
5 + (-5) = 0
Right square: 5
Left square : -5
c) Right square: (-3)
-12 ÷ 4 = (-3)
Down square : 1
4 + (-3) = 1
[tex]\sf d) up \ square: \dfrac{-1}{6}\\\\[/tex]
[tex]\sf \dfrac{1}{2}*\dfrac{-1}{3}=\dfrac{-1*1}{2*3}=\dfrac{-1}{3}\\\\\\Down \ square : \dfrac{1}{6}\\\\\\\dfrac{1}{2}+\dfrac{-1}{3}=\dfrac{1*3}{2*3}+\dfrac{-1*2}{3*2}[/tex]
[tex]\sf = \dfrac{3}{6}+\dfrac{-2}{6}\\\\=\dfrac{3 + (-2)}{6}\\\\=\dfrac{1}{6}[/tex]
