@NAIRA680411 @Simi_2210_ Answer is found by multiplying the number before and the number after the given number

For example, for 3, 2x4=8

So for 7, 6x8=48

Hey @Apple , fix this

iPhone 14 Pro, IOS 26.3.1

Ever since upgrading to IOS 26 I have this notification in Settings, but every time I click on it I get this error message

Wifi or cellular, nothing fixes it

Homeward bound from an enormously enjoyable #ASERA55

Organising committee Jared Carpendale, Carrie Swanson and Cathy Buntting did a superb job: every detail was not only taken care of but showed real thoughtfulness

Thanks to the team, and onward to #ASERA56

“… it will include Muslim candidates from Western Sydney, it will be a disaster’

Imagine it being said about any other group.

Eg “… it will include Jews from the Eastern Suburbs”

“… it will include Indigenous people from the NT”

Should be a career ending statement.

2024.

Still

Seems to be getting closer, but there’s more work to do
