to do it in mental math: you can ignore the zeroes in 400 for now.
4*14 = 4*10 + 4*4 = 40 + 16 = 56
now add the zeroes back on: 5600m
First remember that sum means to add. now think about the equation. we need to find 3 numbers that equal 159 when added together. And they are all consecutive odd numbers. so let's call the first number X. the second number would be X+2 since we have to jump over 1 even number. The third number would be X+4 since we have to jump over 2 even numbers. so now an equation to represent this would be X+(X+2)+(X+4)=159. Add like terms, and remember order of operations. if you need help getting the answers leave me a comment.
Stir salt and water in a saucepan over heat 4-5 minutes.
Remove from heat; add cornstarch and cold water.
Stir until smooth; return to heat and cook until thick.
Allow the clay to cool, then shape as desired.
When dry, decorate with paint, markers, glitter, and so on.
