{0.4), (-4,-6)

Multiple: 0 * 4 = 0
Conversion a decimal number to a fraction: -4 = -4/1 = -4./1

a) Write down the decimal -4 divided by 1: -4 = -4/1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
-4/1 =
Note: is called a decimal fraction.

c) Simplify and reduce the fraction
= 0 * 1/0 * 1 = 0 * 1/0 * 1= 0/0
Subtract: -4 - 6 = -10

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
