Question

topic: properties and laws of whole numbers progress the assessment of the progress test may be uneven because questions can be worth more, more or more challenging. which of the following equations is true? \\( 4 + 1 = 4 \cdot 0 \\) \\( 10 \cdot 1 = 0 + 10 \\) \\( 2 \cdot 1 \cdot 0 = 2 + 1 + 0 \\) \\( 1 + 1 = 1 \cdot 1 \\)

Explanation:

Step1: Evaluate Option 1

Left side: $4+1=5$, Right side: $4-0=4$. $5
eq4$, so false.

Step2: Evaluate Option 2

Left side: $10-1=9$, Right side: $0+10=10$. $9
eq10$, so false.

Step3: Evaluate Option 3

Left side: $2-1-0=1$, Right side: $2+1+0=3$. $1
eq3$, so false.

Step4: Evaluate Option 4

Left side: $1+1=2$, Right side: $1-(-1)=2$. $2=2$, so true.

Answer:

D. $1+1=1-(-1)$
