SUMMARY

This discussion focuses on solving formulas with given variable values, specifically using the example where x, y, and z are initialized to 1. The calculation involves substituting the values of y and z into the formula x = y * z, resulting in x = 1. After updating z with the operation z = z + 1, the new value of z becomes 2, while y remains unchanged at 1. The final values are x = 1, y = 1, and z = 2.

PREREQUISITES
  • Basic understanding of algebraic formulas
  • Familiarity with variable assignment
  • Knowledge of arithmetic operations
  • Experience with mathematical problem-solving techniques
NEXT STEPS
  • Study algebraic expressions and their evaluations
  • Learn about variable manipulation in programming languages
  • Explore mathematical modeling techniques
  • Investigate the use of formulas in data analysis
USEFUL FOR

This discussion is beneficial for students learning algebra, educators teaching mathematical concepts, and anyone interested in understanding variable manipulation in formulas.

Hi how would you solve formula such as this?

example

x=1
y=1
z=1

x = y * z
z = z + 1

x=?
y=?
z=?

(Wave)You just have to replace the values of $y,z$ .

So you have to calculate $x=y \cdot z$ and you know that $y=1, z=1$. Therefore $x=1 \cdot 1=1$.

Then $z=z+1$.We know that $z=1$, so $z=1+1=2$.
The value of $y$ doesn't change , so $y=1$.
