Comment 5 for bug 1582262

Also line 203. mathJs.config({

So I guess it can't find mathJs or something?

Before that, when starting the application there is (among else):
file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/engine/math.js:2854: TypeError: Cannot assign to read-only property "constructor"

If I comment that line out, I'll get:
file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/engine/math.js:2856: TypeError: Cannot assign to read-only property "name"

then:
file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/engine/math.js:7032: TypeError: Cannot assign to read-only property "constructor"

There are also errors like file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/ui/Screen.qml:107: TypeError: Cannot call method 'format' of undefined and file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/ubuntu-calculator-app.qml:361: TypeError: Cannot read property 'dbId' of null

on startup.
